Hydrogen peroxide (H2O2), a valuable chemical, is widely used as powerful oxidizing agent in chemical synthesis, pharmaceuticals, medical disinfection, and environmental treatment industries. Currently, over 95% of H2O2 produced industrially using the anthraquinone process, which associated with its high energy consumption hazardous byproducts. Therefore, photochemical synthesis from water oxygen covalent organic framework based photocatalysts have attracted considerable attention. This review aims to outline recent achievements, challenges future prospects COFs heterogeneous for sustainable generation. We summarize chronological development COFs, different mechanisms involved, detailed experiments quantification methods photocatalytic The puts forward an outlook, highlighting advantages limitations anticipate that this will provide insight into current progress inspire next-generation production.

Owing to their capability produce reactive oxygen species (ROS) under solar irradiation, covalent organic frameworks (COFs) with pre-designable structure and unique architectures show great potentials for water purification. However, the sluggish charge separation, inefficient activation poor stability in COFs restrict practical applications decontaminate water. Herein, via a facile one-pot synthetic strategy, we direct conversion of reversible imine linkage into rigid thiazole can adjust π-conjugation local polarization skeleton boost exciton dissociation on COFs. The also improve robustness during consecutive utilization process. More importantly, optimal C 2p states (COF-S) effectively increases activities neighboring benzene unit directly modulate O2-adsorption energy barrier ROS production efficiency, resulting excellent photocatalytic degradation efficiency seven toxic emerging contaminants (e.g. degrading ~99% 5 mg L−1 paracetamol only 7 min) effective bacterial/algal inactivation performance. Besides, COF-S be immobilized continuous-flow reactor enlarged efficiently eliminate pollutants natural sunlight demonstrating feasibility application.

Abstract Two‐dimensional covalent organic frameworks (2D‐COFs) have recently emerged as fascinating scaffolds for solar‐to‐chemical energy conversion because of their customizable structures and functionalities. Herein, two tris(triazolo)triazine‐based COF materials (namely COF‐JLU51 COF‐JLU52) featuring large surface area, high crystallinity, excellent stability photoelectric properties were designed constructed the first time. Remarkably, gave an outstanding H 2 O production rate over 4200 μmol g −1 h with reusability in pure water under one standard sun light, that higher than its isomorphic COF‐JLU52 most reported metal‐free materials, owing to superior generation, separation transport photogenerated carriers.
