[manufacture method of Photocatalyst Composite 1]
Next, the manufacture method of explanation Photocatalyst Composite 1.The manufacture method of Photocatalyst Composite 1 is without spy
Do not limit, for example, following manufacture method is contemplated that, wherein including:Dispersion step, makes absorbent particles 2 and photocatalyst granular
3 from the surface of Photocatalyst Composite 1 towards inner dispersion.
Specifically, in above-mentioned dispersion step, by powdered absorbent particles 2 and powdered photocatalyst granular
3 mixing, the aggregate of these particles are fixed and are configured to bulk.That is, the manufacture method of Photocatalyst Composite 1 is included:To inhale
Attached dose of particle 2 and the mixed processes of the mixing of photocatalyst granular 3;And make the He of absorbent particles 2 mixed by mixed processes
The forming process of the shaping of photocatalyst granular 3.Thus, Photocatalyst Composite 1 can be manufactured.
In addition, the condition shaped according to the fixation, can form space 6 in Photocatalyst Composite 1.For example, by powder
The absorbent particles 2 of last shape and powdered photocatalyst granular 3 are mixed with certain ratio, and the aggregate of these particles is fixed
After shaping (inside of Photocatalyst Composite 1 fixed shaping) is the bulk with space, will be powdered around it
Absorbent particles 2 and powdered photocatalyst granular 3 are mixed in other ratios, and by same or other shaping sides
Method makes its with carrying space fixed shaping (the fixed shaping on the surface of Photocatalyst Composite 1), to form free thus, it is possible to manufacture
The Photocatalyst Composite 1 of gap 6.In addition, in the manufacture method, as long as the powdered adsorbent when making each fixed shaping
Grain 2 is identical with the ratio of powdered photocatalyst granular 3, can just manufacture the ratio of components of absorbent particles and photocatalyst granular
Uniform Photocatalyst Composite.
The manufacturing process of Photocatalyst Composite 1 is not particularly limited, and can be carried out by ring mould mode or flat-die mode
Granulation, or can also be granulated by cuber.Can apply to other prilling process of the manufacture of Photocatalyst Composite 1
Spray drying, extruding pelletization can be enumerated, granulation, thermoforming granulation etc. is rotated.
In addition, in the case of by granulating manufacture Photocatalyst Composite 1, except absorbent particles 2 and photochemical catalyst
Beyond particle 3, it is also possible to mix other compositions.The typical case of other compositions is adhesive.For example, it is also possible to will be used as adhesive
Clay, CMC (carboxymethylcellulose calcium), resinae etc. organic or inorganic adhesive and absorbent particles 2 and photocatalysis
Agent particle 3 is mixed together and shapes, and thus manufactures Photocatalyst Composite 1.
So manufacture Photocatalyst Composite 1 from process and decompose object impregnability from the viewpoint of, preferably into
Shape is approximately spherical.Be configured to it is approximately spherical in the case of particle diameter (diameter) be not particularly limited, preferably such as 0.5mm with
On, the degree of below 5mm.In other words, particle diameter (diameter) is preferably formed as more than 0.5mm, the bullet form of the degree of below 5mm
Photocatalyst Composite 1.If particle diameter is less than 0.5mm, it may happen that difficult in terms for the treatment of, if greater than 5mm, then
It is possible that problem in terms of the impregnability of object is decomposed.
[effect of Photocatalyst Composite 1]
Then, the effect of Photocatalyst Composite 1 is illustrated.As described above, Photocatalyst Composite 1 includes absorbent particles
2 and photocatalyst granular 3.Absorbent particles 2 and photocatalyst granular 3 can adsorb and/or decompose Photocatalyst Composite 1
Decompose object.Decompose the free position that object can be gas or liquid.Decomposing object can enumerate such as toluene, two
Odorous substances such as the volatile organic solvents such as toluene, acetaldehyde (VOC), acetic acid, hydrogen sulfide, methyl mercaptan etc..Photocatalyst Composite 1
With by adsorbing or decomposing this decomposition object so as to the effect being removed, the use such as smelly eliminating, deodorant is thus suitable for
On the way.
Absorbent particles 2 typically have following feature:Adsorption rate is fast, but cannot proceed to inhale if saturation
It is attached.On the other hand, photocatalyst granular 3 typically has following feature:Decomposition rate is slow, but will not saturation and can persistently divide
Solution.Therefore, if absorbent particles 2 and photocatalyst granular 3 combined, absorbent particles 2 can rapid adsorption decomposition object
Thing, and the decomposition object decomposition for being adsorbed absorbent particles 2 using photocatalyst granular 3.Therefore, absorbent particles 2 are not
Can saturation.On the other hand, the decomposition rate of photocatalyst granular 3 depends on the concentration for decomposing object.When photocatalyst granular 3
When decomposition object to being adsorbed in absorbent particles 2 with high concentration is decomposed, decomposition rate also accelerates.Therefore, photocatalysis
Agent composition 1 can obtain absorbent particles 2 will not saturation and photocatalyst granular 3 the fast synergy of decomposition rate.
In the Photocatalyst Composite 1 of present embodiment, absorbent particles 2 and photocatalyst granular 3 are with dispersity
In the presence of.Thus, for example Photocatalyst Composite 1 is arranged in the gaseous environment for wanting to be removed, thus, it is possible to utilize adsorbent
The effect of particle 2 is adsorbed to removing object gas, and then photocatalyst granular 3 absorbs light, thus, it is possible to utilize photochemical catalyst
The effect of particle 3 will remove object gas and decompose.
In addition, in Photocatalyst Composite 1, photocatalyst granular 3 not only disperses to be present in Photocatalyst Composite 1
Most surface, also dispersion are present in inside.But, absorbent particles 2 have at least one party in transmitance and light reflective.Cause
This, in the case where absorbent particles 2 have transmitance, light can directly reach the photocatalyst granular 3 of inside.In addition,
Space 6 is formed with Photocatalyst Composite 1, therefore in the case where absorbent particles 2 have transmitance and with light
In the case of reflexive, light can be transferred through the photocatalyst granular 3 that space 6 reliably reaches inside.Particularly, zeolite, Hai Pao
The mineral such as stone are lower in the then absorptivity more long of the wavelength region medium wavelength from visible ray near ultraviolet, and light transmission reflects with light
Rate sum is higher.Therefore, as long as making absorbent particles 2 include transmitance zeolite high, sepiolite or their mixture,
The photocatalyst granular 3 inside enough light arrival can just be made.
So, in the Photocatalyst Composite 1 of present embodiment, with transmitance and light reflective at least one
The absorbent particles 2 and photocatalyst granular 3 of side exist with dispersity.Thus, can easily be processed, absorption will not be hindered
The adsorption capacity of agent particle 2 and ensure the photocatalyst granular 3 of q.s.Decomposed accordingly, it is capable to provide and play gas absorption high
Performance, gas decomposability is not easy to the Photocatalyst Composite 1 for reducing during long-term use.So as to can provide can make adsorbent
The absorption property of particle 2 and the lasting Photocatalyst Composite 1 of the decomposability of photocatalyst granular 3.In addition, can provide can be simultaneous
Turn round and look at the Photocatalyst Composite 1 of the decomposability of the absorption property and photocatalyst granular 3 of absorbent particles 2.
In addition, being formed with space 6 in the Photocatalyst Composite 1 of present embodiment.Thus, have in absorbent particles 2
In having a wavelength region of light reflective, also can be same with the wavelength region with transmitance, pass light through space 6 and reach light and urge
The inside of agent composition 1.In addition, decomposing object can be impregnated with space 6, and can be in the absorption inside Photocatalyst Composite 1
Adsorbed in agent particle 2.In addition, relative to 100 volume % of Photocatalyst Composite 1, make space 6 with 30 volume % with
The upper, ratio of below 50 volume % is formed, thus, it is possible to more reliably make light reach the inside of Photocatalyst Composite 1, and energy
Decomposition object is set fully to be adsorbed in the absorbent particles 2 of the inside of Photocatalyst Composite 1.

Accept with equal ability (velocity of gas sorption=1.6 [h-1]).
(evaluation method)
Fig. 2 is to show that the measurement system evaluated for the gas absorption decomposability for carrying out Photocatalyst Composite 1 (is evaluated
Device 10) skeleton diagram.As shown in Fig. 2 evaluating apparatus 10 include shading case 11, light source 12, gas pouch 13 and culture dish 14.
Light source 12 is set by the direction shone on the ground from the internal roof center of shading case 11.Gas pouch 13 is arranged at the ground of shading case 11

Between transmitted through structure, the light beyond the light sent from light source 12 will not be irradiated to gas pouch 13.Light source 12 use wavelength for
The blue led of 450nm, is irradiated with the radiant illumination of about 7mW/cm2.Gas pouch 13 has the capacity of 5L, in wavelength 450nm
It is nearby transparent, is that can be confined to the structure that gas cannot come in and go out.Culture dish 14 is made up of quartz glass, herein place want into
The object (Photocatalyst Composite 1) of the measure of promoting the circulation of qi body adsorption-decomposition function speed.
Decompose object gas using aldehydes gas as VOC, as various smells the reason for gas representative.Determine gas
The time dependence of bulk concentration change, is taken as the logarithm of gas concentration, when transverse axis is taken as the time, by the size of slope in the longitudinal axis

In, the Photocatalyst Composite for being also shown for being supported with photocatalyst granular as the surface in ceramics of comparison other (compares
Example 1) measurement result.
As shown in figure 3, in comparative example (ceramics+photochemical catalyst (surface supports)), in the absence of absorbent particles 2, therefore
If not carrying out the adsorption-decomposition function that light irradiation is hardly visible gas.But, photochemical catalyst is occurred in that by carrying out light irradiation
The effect of grain, gas absorption decomposition rate is determined as 0.8 [h-1].
And in the Photocatalyst Composite 1 (zeolite+photochemical catalyst mixing bullet) of evaluation object, when not carrying out light irradiation
Gas adsorption rate be 1.5 [h-1], by carrying out light irradiation, gas decomposition rate rises to 2.8 [h-1].
It follows that not being that the effect of absorbent particles 2 and light are urged in the Photocatalyst Composite 1 of present embodiment
The simple addition of the effect of catalyst particles 3, and gas absorption decomposability higher has been played by synergy.
Next, illustrating the Photocatalyst Composite 1 of present embodiment and showing as comparison other using Fig. 4~Fig. 7
The ratio of some Photocatalyst Composites (being supported with the Photocatalyst Composite of photocatalyst granular on the surface of absorbent particles)
Relatively result.Fig. 4 is the figure for showing to shoot Photocatalyst Composite 1 SEM image for obtaining.Fig. 5 is shown to as relatively more right
As the existing Photocatalyst Composite of (comparative example 2) shoots the figure of the SEM image for obtaining.
In the past, as described in above-mentioned patent document 1,2, the hand of absorbent particles and the combined effect of photocatalyst granular is played
What section was taken is photocatalyst granular is supported in the method on the surface of absorbent particles.Its design is, in order that photochemical catalyst
Gas etc. is decomposed object decomposition and needs irradiation light by particle, and photochemical catalyst is configured into the absorbent particles in easy irradiation light
Surface.
And in the Photocatalyst Composite 1 of present embodiment, photocatalyst granular 3 not only disperses to be present in photochemical catalyst
The surface of composition 1, also dispersion is present in inside.
As described above, the Photocatalyst Composite (comparative example 2) of the Photocatalyst Composite 1 of evaluation object and comparison other
Zeolite is used as absorbent particles, the composition of proportions of degree of the photocatalyst granular 3 with weight than about 10~20%.
As shown in figure 4, on the surface of the Photocatalyst Composite 1 of evaluation object, particle diameter is for about the zeolite of 0.5 μm of degree
Particle (absorbent particles 2) largely exposes, and is found everywhere the particle of the photocatalyst granular 3 of the degree that particle diameter is for about 0.1 μm.
And it is as shown in Figure 5, it is known that in the Photocatalyst Composite of comparative example 2, the surface base of zeolite (absorbent particles)
This is covered by photocatalyst granular.In this composition, what is exposed on surface is photocatalyst granular, and zeolite does not reveal on surface
Go out, therefore gas absorption performance cannot be given full play to.
Next, illustrating that Photocatalyst Composite 1 and the actual gas of existing Photocatalyst Composite are inhaled based on Fig. 6
The measurement result of attached performance.Fig. 6 is by the gas of Photocatalyst Composite 1 and existing Photocatalyst Composite (comparative example 2)
The coordinate diagram that absorption property is compared.Additionally, in figure 6, as a comparison, being also shown for not being supported with photocatalyst granular
The measurement result of the velocity of gas sorption of the single bullet of zeolite.
As shown in fig. 6, the gas absorption of the Photocatalyst Composite 1 (zeolite+photochemical catalyst mixing bullet) of evaluation object
Speed is 1.5 roughly the same [h-1] with the bullet of only zeolite.
And the velocity of gas sorption of the Photocatalyst Composite (zeolite bullet+photochemical catalyst (surface supports)) of comparative example 2
It is 1.2 [h-1], it is known that compared with the Photocatalyst Composite 1 and single zeolite of evaluation object, gas absorption performance is relatively low.
Accounted for reference to the result of the SEM image of Fig. 5 and the result of Fig. 6, it is contemplated that because zeolite surface is urged by light
Catalyst particles are covered, therefore photocatalyst granular 3 brings negative effect to the gas absorption performance of absorbent particles 2.
Next, illustrating that Photocatalyst Composite 1 and the actual gas of existing Photocatalyst Composite are inhaled based on Fig. 7
The measurement result of attached performance.Fig. 7 is by the gas of Photocatalyst Composite 1 and existing Photocatalyst Composite (comparative example 2)
The coordinate diagram that decomposability is compared.
As shown in fig. 7, gas decomposition rate is 2.8 [h-1].The result shows, even such as Photocatalyst Composite 1
Such photocatalyst granular 3 is present in the composition of the inside of bullet, by using absorbent particles 2 with transmitance and can
See the photocatalyst granular 3 of photoresponse type, light can also sufficiently achieve the photocatalyst granular 3 of inside.It is thus identified that photocatalysis
Agent composition 1 has and the Photocatalyst Composite for making photocatalyst granular support the comparative example 2 in the surface of absorbent particles
(zeolite bullet+photochemical catalyst (surface supports)) is the gas decomposability of same degree.
On the other hand, in the Photocatalyst Composite of comparative example 2, photochemical catalyst is supported with zeolite bullet surface
Grain, thus by long-term use just in case in the case of occurring to come off chip etc. from bullet, can be preferential from being present in surface
Photocatalyst granular it is peeling-off.As a result, gas decomposability constantly declines, only absorbent particles are eventually become
Bullet.
And in Photocatalyst Composite 1, until inside all there is photocatalyst granular 3, even if therefore long-term use,
Gas decomposability can be made to continue without being wholly absent.Accordingly, it is capable to realize long-life Photocatalyst Composite 1.
Additionally, in Photocatalyst Composite 1, the ratio (ratio of components) of absorbent particles 2 and photocatalyst granular 3 is at it
Each internal position is uniform.Thus, even if there occurs that chip comes off, the ratio of absorbent particles 2 and photocatalyst granular 3
Example is also fixed.Therefore, in Photocatalyst Composite 1, total energy keeps absorption and the optimum balance for decomposing.In addition, inhaling
In the case that attached dose of particle 2 and photocatalyst granular 3 are extremely consumed, by additional supplement identical Photocatalyst Composite 1,
And the balance of absorption and decomposition can be kept and recover gas absorption decomposability.
As described above, in Photocatalyst Composite 1, absorbent particles 2 and photocatalyst granular 3 are deposited with dispersity
, therefore can continue absorption property and decomposability.
