Description
Technical field
The invention belongs to new material, utilization of new energy resources and technical field of environment pollution control, are related to a kind of high activity MoS2/
g-C3N4/Bi24O31Cl10The preparation method of composite photo-catalyst.
Background technique
With the increasingly exacerbation of problem of environmental pollution, photocatalysis technology is in terms of photolysis water hydrogen and degradable organic pollutant
More and more paid attention to.Wherein, TiO2Have many advantages, such as that at low cost, photocatalysis stability is good, photocatalysis efficiency is high, is light
Common used material in catalytic field.But TiO2Photochemical catalyst is since its forbidden bandwidth is wide, about 3.1eV, can only by ultraviolet excitation, and
Ultraviolet light only accounts for 5% or so of solar spectrum, low to the utilization rate of sunlight, limits it to a certain extent in environmental improvement
The application of aspect.Therefore, utmostly to utilize solar energy, R and D can be mesh by the new catalyst of excited by visible light
Preceding research emphasis and hot spot.
Bismuth series catalysts are current a kind of novel visible catalysts of greatest concern, it becomes at aspect of curbing environmental pollution
It is now good, increasingly liked by domestic and international researcher.Their most prominent advantages are exactly that forbidden bandwidth is relatively narrow, this
Feature is conducive to its organic pollutant in photocatalytic degradation environment under visible light.Wherein Bi24O31Cl10As a kind of oxygen-enriched
Bismuth series catalysts, due to having the advantage that forbidden bandwidth is small, about 2.8eV can be by excited by visible light；It is chemically and physically stable
Property is good；It is high with unique crystal structure, quantum efficiency, just becoming research hotspot in recent years.Such as Jin uses hydro-thermal legal system
For with a thickness of 300nm, the Bi that width is 1-3 μm24O31Cl10Photochemical catalyst, compared with BiOCl, Bi24O31Cl10In visible light
Visible light can be preferably absorbed under (> 420 nm) irradiation, and effectively can generate O by activating molecules oxygen2·-, to enhance
Bi24O31Cl10Visible light photocatalysis active.The method that Yin etc. is combined using hydro-thermal and heat treatment, is prepared for Bi24O31Cl10
Nanometer sheet is used for the degradation of quadracycline, illumination 150min under visible light, to the degradation rate of quadracycline up to 80% with
On.However, pure Bi24O31Cl10Photoproduction-electron hole it is easily compound, and specific surface area is smaller, causes its photocatalytic activity lower,
Actual industrial application is not able to satisfy still, for this purpose, also need to adopt various measures to improve its photocatalytic activity, such as by energy band position
It is compound to set the different semiconductor materials progress to match, forms hetero-junctions, the compound of material internal electrons and holes can be reduced
Rate.
MoS2It is the photon that a type graphene hexagonal closs packing layer structure material can absorb visible frequency, and it is led
The edge current potential of band and valence band is high, when compound with other photochemical catalysts, can effectively enhance the absorbability to light, and can play fast
The effect of speed transmission electronics.And g-C3N4It is a kind of polymer semiconductor similar to graphene-structured, C, N atom are with sp2 hydridization
Form the pi-conjugated system of height delocalization.g-C3N4Have many advantages, such as that the from a wealth of sources of polymer material, price be low, chemical stabilization,
And have certain absorption to visible light, there is preferable photocatalysis performance.And MoS2With g-C3N4Valence band and conduction band positions with
Bi24O31Cl10Energy good match, forms hetero-junctions, on the one hand enhances Bi24O31Cl10Light absorpting ability, and can effectively subtract
Few Bi24O31Cl10The recombination rate of internal electron and hole, and in Bi24O31Cl10The thin layer MoS of particle surface cladding2With g-C3N4
Nanometer sheet increases the specific surface area of catalyst, the pre- adsorbance of catalyst surface in organic pollutant is increased, to also have
Conducive to the raising of light-catalyzed reaction efficiency.
In view of this, it is necessary to provide a kind of MoS2/g-C3N4/Bi24O31Cl10The preparation method of heterojunction photocatalyst.
Summary of the invention
To solve the above problems, the present invention provides a kind of high activity MoS2/g-C3N4/Bi24O31Cl10Composite photo-catalyst
Preparation method.
Preparation method of the invention, first using bismuth nitrate, ammonium chloride, citric acid as raw material, the improvement solution combustion of use
Method prepares Bi24O31Cl10, the then ultrasonic disperse in methanol solution；Secondly using melamine, acetic acid as raw material, using step heat
Polymerization prepares g-C3N4, the then ultrasonic disperse in methanol solution；Using ammonium molybdate, thiocarbamide as raw material, dimethylformamide is molten
Agent prepares MoS using hydro-thermal method2, ultrasonic disperse is handled in methanol solution.It will finally handle through ultrasonic disperse
Bi24O31Cl10With g-C3N4、MoS2It is dry after then washed, centrifugation after ultrasonic mixing is sufficiently reacted in methanol solution, i.e.,
Obtain MoS2/g-C3N4/Bi24O31Cl10Composite photo-catalyst.
