Metal‐organic framework derived materials received a lot of attention due to their significant benefits in photocatalytic reactions. In this work, a Z‐scheme ZnIn2S4/Bi2S3 hierarchical heterojunction is first developed by a one‐pot method using CAU‐17 as a template. The specific preparation method endows an intimate interface contact between these two monomers, and CAU‐17‐derived Bi2S3 possesses a high surface area and porosity, resulting in an efficient charge separation and O2 capture. Thus, for photocatalytic H2O2 production from the O2 reduction reaction, the ZnIn2S4/Bi2S3 heterojunction can achieve an H2O2 yield of 995 µmol L−1 in pure water and ambient air under visible light, 4.5 and 4 times that of ZnIn2S4 and Bi2S3, respectively. In addition, in tetracycline solution, ZnIn2S4/Bi2S3 can degrade tetracycline with a degradation rate of 95% by photocatalysis, and at the same time, a final H2O2 production yield of 1223 µmol L−1 is reached. Similarly, high yields of H2O2 are also obtained from wastewater containing o‐nitrophenol, acid golden yellow, or acid red, and these pollutants are effectively degraded. This work reveals the potential of metal‐organic framework‐derived materials in photocatalysis, as well as provides insights into H2O2 green synthesis and wastewater treatment.
