Abstract Semiconductor materials can absorb visible light to become excellent hydrogen-producing materials. When different semiconductors are supported on each other, it can greatly promote the increase of hydrogen production rate. The article uses ZnS and CoMoO4 to construct a new type of S-scheme heterojunction, and uses related characterization to illustrate the hydrogen production advantages and high performance reasons of the system. The experimental data of photocatalytic hydrogen production concretely proved the high catalytic performance of the composite material. The results shown that when the amount of ZnS loaded on CoMoO4 was 5%, the adsorption of the composite catalyst and an appropriate amount of sensitizer made the hydrogen production rate reached 1233 μmol/g/h. This study used different characterizations to show the ball-and-stick structure of the composite catalyst and supplements the S-scheme heterojunction mechanism. Based on various studies, ZnS and CoMoO4 had broad application prospects. The special electron transfer path of the S-scheme heterojunction provided theoretical model support for high-performance hydrogen production.
