The rational construction of heterojunction interfaces plays a critical role in enhancing the carrier separation efficiency for photocatalytic hydrogen evolution. In this study, ZnIn2S4/H2WO4 S-scheme was successfully synthesized via self-assembly strategy. Compared with conventional WO3, H2WO4 component exhibits lower work function, which significantly promotes surface electron overflow and establishes an optimized charge transfer pathway. Structural characterization reveals that intimate integration nanosheets within ZnIn2S4 nanoflowers provides enhanced interfacial contact, thereby facilitating efficient migration. As result, composite demonstrates evolution rate 138 mmol/g/h, achieving 4.7-fold enhancement over pristine 1.9-fold improvement compared to ZnIn2S4/WO3. This highlights dual requirements oxidation photocatalysts systems: precise band gap alignment favorable electronic properties, both essential enabling ensuring effective migration channels.
