This study in situ prepared ZnIn₂S₄ (ZIS) nanoflowers onto a hollow covalent organic framework to strategically engineer a type-II organic–inorganic core–shell heterojunction photocatalyst, transforming O₂ into H₂O₂. The heterojunction photocatalyst exhibited an exceptional H₂O₂ productivity of 3334 μmol g⁻¹h⁻¹ when no sacrificial agent was added, surpassing most reported systems. Mechanistic studies revealed that the heterojunctions extended the light absorption spectrum toward longer wavelengths and significantly increased the probability of electron transfer from photogenerated carriers to reactive species, which accelerated the reduction of O₂ to H₂O₂. Furthermore, theoretical calculations confirmed that the heterojunction formation modified the coordination environment of the active sites on ZIS, fine-tuned the binding interaction between O₂ and the catalyst interface, and reduced the energy barrier of intermediates, leading to superior performance.
