NOVELTY - Synthesis of rhodium-induced growth of zinc oxide-zinc sulfide heterostructure photocatalyt involves dispersing graphene oxide in deionized water, preparing gray-black flocs by weighing zinc powder and adding to the solution, stirring and combining into stable gray-black floc through redox reaction, using pipette to drip rhodium(III) chloride trihydrate solution into the system, stirring and performing displacement reaction to attach the metal rhodium on surface of zinc powder, transferring the system to suction filtration bottle, placing in oven for constant temperature reaction and subjecting the system to vacuum operation, collecting obtained product and filtering, washing with water and drying to obtain rhodium-zinc oxide/reduced-graphene oxide solid catalyst, and taking the solid catalyst and adding thioacetamide, stirring and refluxing in constant temperature water bath and filtering to obtain rhodium-zinc oxide/reduced-graphene oxide/zinc sulfide catalyst, washing and drying. USE - Synthesis of rhodium-induced growth of zinc oxide-zinc sulfide heterostructure photocatalyt used for producing hydrogen. ADVANTAGE - The method uses graphene oxide as dispersant to construct the photocatalyst for in-situ induced growth of rhodium, the recombination of photogenerated carriers of the photocatalyst is reduced, and compared with pure phase zinc oxide, the hydrogen production performance is greatly improved. DETAILED DESCRIPTION - Synthesis of rhodium-induced growth of zinc oxide-zinc sulfide heterostructure photocatalyt involves dispersing graphene oxide by adding preset amount of graphene oxide solution to beaker containing deionized water and fully stirring, preparing gray-black flocs by weighing preset amount of zinc powder and slowly adding to the solution and fully stirring and combining the two into stable gray-black floc through redox reaction, using pipette to slowly drip rhodium(III) chloride trihydrate solution with specific concentration into the system and stirring to make it fully mixed and performing displacement reaction, where the metal rhodium can be firmly attached on surface of zinc powder, transferring the system to suction filtration bottle, placing in oven for constant temperature reaction and subjecting the system to vacuum operation at certain time interval, collecting obtained product and filtering, washing with water and drying to obtain rhodium-zinc oxide/reduced-graphene oxide solid catalyst, and taking preset amount of the solid catalyst and adding preset amount of thioacetamide in proportion to round-bottomed flask containing 50 mL deionized water, obtaining the solid catalysts with different sulfide degrees by stirring and refluxing in constant temperature water bath for different times and filtering to obtain rhodium-zinc oxide/reduced-graphene oxide/zinc sulfide catalyst, washing and drying.
