Description
Technical field
The invention belongs to technical field of air purification more particularly to a kind of light catalytic purifying gas laminate film photocatalysis
Agent, preparation method and application.
Background technique
Volatile organic matter (VOCs) is one of haze inducement and room air major pollutants.Removing volatility has
Machine object, which administers atmospheric environment, living environment improves has very big meaning.
Traditional VOCs Treatment process includes absorption method, condensation method, combustion method, Production by Catalytic Combustion Process, biological degradation method etc..This
A little VOCs degradation techniques have preferable regulation effect for corresponding contamination sources.However due to its operating cost height, poor reliability,
The factors such as complicated for operation, secondary pollution, above-mentioned traditional technology are not particularly suited for the field of gas purification under normal temperature and pressure conditions.Light
Catalysis technique can be realized carries out VOCs oxidation (removing) reaction under normal temperature and pressure conditions, has mild condition, easy to operate, nothing
The advantages such as secondary pollution and operating cost are low.For the outer density of field energy, the more other thermal fields of Light Energy density, electric field etc.
Low, therefore, photocatalysis technology is a kind of dirty suitable for low concentration VOCs in gas phase in environmental area, especially field of gas purification
Contaminate the degradation removing sulfuldioxide of object.
Light-catalyzed reaction is the chemical reaction of light energy field driving.When light energy is greater than the forbidden band energy width of catalyst,
Isolated electron-hole pair is generated, i.e., transits to conduction band and valence band respectively, forms corresponding physical activity in catalyst surface
At site, two half-reactions occur.Oxidation half-reaction occurs at the corresponding physical activity site of valence band (hole)；Conduction band (electronics)
Reduction half-reaction occurs at corresponding physical activity site.Therefore, light-catalyzed reaction, with isolated oxidation reaction, reduction reaction
It is characterized, is two half-reactions being separated from each other.Common semiconductor light-catalyst (such as TiO2), due to inhaling with large bandwidth
Receipts, which only account for 5% ultraviolet light of solar spectrum, just has photocatalytic activity.It is loaded by catalyst modification, such as on the semiconductor
The light abstraction width of semiconductor light-catalyst can be extended to visible light region by ion excimer type metal nanoparticle.
Compared to conventional powder type photochemical catalyst, laminate film photochemical catalyst is carried due to unique in structure
Body thin film as photochemical catalyst bottom, after support (plasmon type metal) active constituent and, as top layer, be thusly-formed stacking
Film photocatalyst.Absorption for two-dimentional light energy field, film are higher compared with the photochemical catalyst utilization rate of powder morphology, thus light
Catalyst amount greatly reduces (cost decreases), and Adhesion enhancement of the laminate film photochemical catalyst in substrate is (durable
Property increases accordingly).After catalyst inactivation, laminate film photochemical catalyst self-stick notes, easily removal update.Since carrier thin film itself is made
Standby technical difficulty and its metal nanoparticles loaded process difficulty are bigger, at present still without light catalytic purifying gas laminated thin
Film photocatalyst and its self-stick notes technology, especially towards the light catalytic purifying under the conditions of visible light (sunlight, indoor light source)
Gas laminate film photochemical catalyst and its self-stick notes technology.
Summary of the invention
In order to the problems of solve in the prior art, the present invention provides a kind of light catalytic purifying gas laminated thins
Film photocatalyst, preparation method and application.
Specific technical solution is：
A kind of light catalytic purifying gas laminate film photochemical catalyst is heterogeneous multilayered structure, uniformly attached on substrate
One layer of carrier, one layer of active component of uniform load on carrier；Wherein, the carrier is TiO2、CdS、ZnO、SiO2、
Al2O3、ZrO2、CeO2、Fe2O3One or more of mixing, one or both of active constituent Au, Ag, Cu with
Upper mixing.
Further, the film thickness that above-mentioned carrier is formed is nanoscale to micron order；Active constituent matter in the catalyst
Measuring percentage is 0.1-60%, and unit area loading is 0.01 μ g/cm2–1g/cm2。
Further, the preparation method of above-mentioned light catalytic purifying gas laminate film photochemical catalyst, which is characterized in that
Include the following steps：
(1) using chemical vapour deposition technique will carrier predecessor uniform deposition corresponding with carrier in substrate material surface
On, to form carrier thin film；
(2) active constituent is carried on the carrier thin film using deposition-precipitation；
(3) activated to obtain the laminate film photochemical catalyst for being attached to substrate.
Further, above-mentioned base material attached catalyst side used, in carrier predecessor uniform deposition in base material
Before, it is surface-treated through plasma method, to enhance adhesive force of the laminate film photochemical catalyst on substrate material surface.
Further, above-mentioned substrate is polymeric film material or rigid base material；The polymeric film material is poly-
Acid imide, polytetrafluoroethylene (PTFE), polyether-ether-ketone, polyethylene or polypropylene；The rigid base material is quartz glass, common glass
Glass or sheet metal.
Further, above-mentioned steps (1) carrier predecessor uniform deposition is after on substrate material surface through calcination process, roasting
Burning temperature is 300~900 DEG C, and calcining time is 0.5~5h, so that catalyst carrier film has certain degree of crystallization and more
It is solid and reliable.
Further, the activation of above-mentioned steps (3) is using roasting and/or plasma method.
Further, the maturing temperature of above-mentioned activation is 100~500 DEG C, and calcining time is 0.5~5h.
Further, above-mentioned plasma method is to be put using one or more of oxygen, argon gas or nitrogen
Electricity generates plasma and is surface-treated.
The application of above-mentioned light catalytic purifying gas laminate film photochemical catalyst, substrate are coated relative to the other side of carrier
Sticky agent with adhesive attachment function forms laminate film photochemical catalyst self-stick notes；Under illumination condition, by laminate film light
Catalyst or its convenience adhere in air atmosphere, carry out the volatile organic matter in photocatalysis removing air；The air
Atmosphere is the indoor and outdoor air with mobility, and temperature is room temperature or outdoor temperature, and humidity is the atmosphere natural humidity of indoor and outdoor
Or having the humidity of humidification, illumination is indoor and outdoor sunlight, visible light source or ultraviolet source.
Since illumination is two-dimentional energy field, illumination is the requirement of light-catalyzed reaction.The absorption of visible light and visible light
The contribution of catalysis reaction mostlys come from active component.Compared to the photochemical catalyst of powder-type, absorption for light, laminate film
Active component in photochemical catalyst has higher efficiency.Since active component is whole only in catalyst in laminate film photochemical catalyst
Surface, active component efficiency is also higher in light-catalyzed reaction.
Beneficial effects of the present invention：The present invention is by light catalytic purifying gas laminate film photochemical catalyst or its convenience
