Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in further detail by technical scheme and embodiment.
Embodiment one, according to Fig. 1,2,3,4, a kind of cadmium sulfide C-base composte material is as the preparation of photoelectric
Method, specifically comprises the following steps that
Step one, utilize carrageenan gel principle that the 2g ι that the mass fraction of high-temperature digestion is 2%-carrageenan raw material is instilled
100ml concentration is in the ethanol solution of the hydrochloric acid of 2mol L-1, forms gel, does gel roguing and processes；
Step 2, carrageenan gel after roguing to be immersed 100ml substance withdrawl syndrome be that the ethanol of 1.5mol L-1 cadmium acetate is molten
In liquid, process 3 ~ 5 times；
Step 3, above-mentioned gel ethanol and moisture being walked cleaning 2 ~ 3 times, the gel after processing is put in refrigerator, then
Lyophilization, forms cadmium-carrageenan aeroge；
Step 4, cadmium-carrageenan aeroge through certain carbonization technique calcining, is calcined 1 hour for 700 DEG C in tube furnace, it
After 610 DEG C of de-carbons 1 hour in carbon dioxide again, obtain cadmium sulfide carbon back composite photoelectric catalyst；
Step 5, use electrochemical workstation and xenon lamp systems test the PhotoelectrocatalytiPerformance Performance of above-mentioned cadmium sulfide C-base composte material.
The cadmium sulfide C-base composte material of Fig. 2 SEM figure, hence it is evident that seen from there is good aeroge pattern, substantial amounts of sulfur
Cadmium nano-particle is on aeroge surface.
Use carrageenan, two acetate hydrate cadmium raw materials, successfully prepare the cadmium sulfide carbon back for photoelectrocatalysis multiple
Close catalyst.This catalyst shows excellent photoelectric catalytically active, and (density of photocurrent 100 μ about A, light source is 300W(100W
Cm-2) xenon lamp, electrolyte is metabisulfite solution) and good light stability (4000 seconds density of photocurrent of continuous illumination are hardly
Become).
The technique of traditional fabrication cadmium sulfide, typically using sodium sulfide or hydrogen sulfide as additional sulfur source, in preparation process
Easily produce secondary pollution, furthermore cadmium sulfide is inhaled owing to hole and photoelectronic quick composite table reveal light in photocatalytic process
The low light stability with extreme difference of rate of producing effects, this greatly limits cadmium sulfide application in photocatalysis.Additionally marine biomass
Greatly developing of material, is we provided development opportunity more.Therefore, stable sulfuration is prepared in development simply and easily
The method of cadmium carbon back composite photoelectric catalyst, thus overcome cadmium sulfide preparation and photoelectrocatalysis in defect it is critical that.
In the present invention, carrageenan abundance, resource are extensive, and gained photoelectrocatalysimaterial material shows the performance of excellence, is
The most promising material for photoelectrocatalysis.
