NOVELTY - General synthesis for in situ construction of indium oxide-modified zinc oxide-zinc sulfide heterostructure, comprises evenly dropwise adding indium nitrate solution to reduced graphene oxide (rGO)-wrapped zinc powder dispersion under continuous stirring; during continuous stirring, free In3+ in solution gradually turns into indium particles and is anchored on surface of zinc powder, forming micro-battery system with zinczinc oxide as the anode and indiumwaterH2 as cathode; where, rGO actively promotes electron transport and transfer in the micro-battery reaction system; indium metal particles will also undergo self-oxidation to generate indium(III) oxide during the micro-battery reaction; after finishing reaction, washing and drying to obtain the indium(III) oxide-zinc oxide/rGO primary product; selecting the indium(III) oxide-zinc oxide/rGO primary product prepared by thioacetamide solution and sulfidation microelectrochemical process, to prepare heterostructure photocatalyst. USE - The heterostructures is useful for photocatalytic hydrogen production from water splitting (claimed). ADVANTAGE - The heterostructures: has high specific surface area, smooth carrier migration, active carrier separation and utilization efficiency, thus improving the photocatalytic hydrogen production activity.
