Sustainable hydrogen peroxide (H(2)O(2)) production is crucial for addressing environmental challenges and advancing chemical synthesis. Photosynthesis of H(2)O(2) from water, oxygen, and light offers an eco-friendly and cost-effective alternative to conventional methods; however, its practical application is limited by the poor performance of traditional photocatalysts due to rapid charge recombination, inefficient charge utilization, and limited redox capability. Herein, we developed a hybrid photocatalyst by integrating MoS(2) nanosheets into a covalent organic framework (COF), forming a MoS(2)-1,3,5-triformylphloroglucinol-4,4',4''-(1,3,5-triazine-2,4,6-triyl)-trianiline (MoS(2)-Tp-TAPT) heterostructure. This structure exhibits enhanced charge separation, reduced charge transfer resistance, and improved stability during photocatalytic reactions in pure water. Control experiments revealed that H(2)O(2) generation proceeds via two synergistic pathways. The optimized 3% MoS(2)-Tp-TAPT catalyst achieved a high H(2)O(2) production rate of 667 mumol g(-1) h(-1), significantly outperforming the pristine COF. This work demonstrates an effective strategy to enhance both the stability and the photocatalytic efficiency of COFs through hybrid structure engineering.
