Abstract Heterojunction photocatalytic materials show great promise in hydrogen production from water decomposition under visible light. The selection of components the heterojunction and type constructed directly determine efficiency. In this study, black phosphorene (BP), which has a broad light absorption range, ZnIn 2 S 4 (ZIS), with suitable band structure, are chosen to design new photocatalysts. Through an ultrasound‐assisted solvothermal method, BP/ZIS unique layered 2D/2D structure is successfully synthesized. Comprehensive characterization calculation have elucidated microstructure BP ZIS, further confirming formation Z‐scheme heterojunction. Such novel exhibits remarkable evolution rate 1317 µmol·h −1 ·g , making 3.35‐fold increase compared ZIS superior performance over BP. This enhancement activity can be primarily attributed enhanced harvesting carrier utilization resulting work provides insights for development efficient photocatalysts production.
