CuInS2Mischcrystal photocatalyst (Cu In) is formed in crystalxZn2(1-x)S2, by the regulation of component, obtain 1.75eV-
The photochemical catalyst of 2.67eV bandgap ranges, Zn introducing causes the light abstraction width of material greatly to increase, and is effectively improved
The utilization ratio of solar energy.Typically by broad-band gap ZnS (Eg=2.5eV) and narrow band gap AgInS2(Eg=1.8eV) synthesize
(Ag In)xZn2(1-2x)S2Photochemical catalyst, and control ZnS and AgInS2Ratio can adjust (Ag In)xZn2(1-2x)S2
Energy gap, with very high photocatalysis hydrogen production efficiency.(the Ag In) of 3wt%Pt loads0.22Znl.56S2At 420nm
The sub- efficiency of hydrogen output reaches 20%.The research such as Zhijun Ning applies the AgInZnS of zero dimension in different solutions pH value, catalysis
Photocatalyzed Hydrogen Production situation under the concentration of agent, the concentration of sacrifice agent and the production hydrogen condition of cocatalyst concentration, optimizes light point
Xie Shui condition.However, regulation and control of the application study also not on CuInZnS quantum dot component copper influence on Photocatalyzed Hydrogen Production.
The content of the invention
It is an object of the present invention to provide one kind with zinc acetate, copper acetate, indium nitrate, thioacetamide, Cys, hydrogen-oxygen
Change sodium to be raw material to synthesize the hydro-thermal being simply easily controlled of the quantum dot light catalyst with good visible photocatalysis water activity
Method.
The present invention is realized by following steps:
(1) the Cys aqueous solution is added in copper acetate, indium nitrate and zinc acetate mixed aqueous solution, then adjusts mixing
The pH of liquid, adds sulphur source, stirring ultrasound, then mixed liquor is poured into water heating kettle, is placed in 110 DEG C of baking ovens and reacts 4 hours.Use water
Precipitation is washed with ethanol, obtained CuInZnS quantum dot light catalyst is stored in water, and controls the accounting of copper acetate, Cu/
In/Zn mol ratios are 0.05/10/5-2.5/10/5, and CIZS-0.05-CIZS-2.5 are designated as respectively.Optimal mole of photocatalysis performance
Than for 1/10/5, i.e. CIZS-1.
The pH value of the regulation mixed liquor refers to:Use concentration for 1 mole every liter sodium hydroxide adjust mixed liquor pH be
8.5。
The mole of thioacetamide and Cys is fixed as 2.4 and 3.7 mMs in building-up process.
(2) the CuInZnS quantum dot light catalyst prepared by the present invention, size is 3-5 nanometers, in aqueous in clarification
Transparent solution, and the accounting containing different Cu sample under same concentrations solution colour fade to red from glassy yellow.
(3) instrument such as X-ray diffractometer (XRD), Flied emission 300kV high-resolution-ration transmission electric-lens, ultraviolet specrophotometer are utilized
Device carries out structural analysis to product, is catalytically decomposed using vulcanized sodium and sodium sulfite as sacrifice agent and platinum as co-catalyst
Water, its photocatalysis performance is assessed with photochemical catalyzing analysis system.
The present invention relates to quaternary CuInZnS is nanocrystalline, CuInZnS is nanocrystalline to can be by component regulation and control bandgap structure
Visible light-responded n-type quaternary semiconductor, size is small, and specific surface area is larger, and such avtive spot is more, extremely beneficial to photocatalysis
Produce hydrogen, and narrower charge migration distance so that electron hole pair quickly can be migrated and separated.The quantum dot system
Valence band is made up of the 2p tracks of sulphur and the 3d tracks of copper, by regulating and controlling amount of copper, to influence the band gap of material, improves the absorption to light
Ability, while reduce copper defect effect with co-catalyst Pt, greatly promote nanocrystalline photoexcited electron hole separation and
Transfer, optimization production hydrogen activity.

Embodiment
The preparation of embodiment 1CuInZnS quantum dot light catalyst
Weigh copper acetate, 0.139 gram of zinc acetate, 0.4867 gram of indium nitrate, mixing is dissolved in 4.125 milliliters of water, here for
The CuInZnS photochemical catalysts of the different accounting amount of copper of synthesis, are separately added into different amounts of copper acetate 0.0127g-0.0635g
(CIZS-0.05-CIZS-2.5), 0.4537 gram of Cys aqueous solution is added after uniform mixing.Again with 1 mole of every liter of concentration
