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.

Abstract The catalytic performance, depending on the surface nature, is ubiquitous in photocatalysis. However, engineering for organic photocatalysts through structural modulation has long been neglected. Here, we propose a zone crystallization strategy covalent frameworks (COFs) that enhances ordering regulator-induced amorphous-to-crystalline transformation. Dynamic simulations show attaching monofunctional regulators to of spherical amorphous precursor improves dynamic reversibility, increasing crystallinity from inside out. resulting COF microspheres display surface-enhanced and uniform morphology. visible photocatalytic hydrogen evolution rate reaches 126 mmol g –1 h simplest β-ketoenamine-linked 350 SiO 2 @COF with minimal Pt cocatalysts. Mechanism studies indicate crystalline domains build electrical fields accumulate photogenerated electrons diminish electron transfer barriers between interface. This work bridges gap microscopic molecules macroscopic properties, allowing tailored design photocatalysts.

Abstract Covalent organic frameworks (COFs), newly developed materials, exhibit considerable promise in the field of catalysis. COFs captivating catalytic characteristics, including thermal and chemical stability, customizable porosities, ability to place active sites flexibly with tunable functions. To establish a connection between structure activity, this paper provides thorough justification planned creation covalent for photocatalysis, encompassing H 2 production, carbon dioxide reduction, pollutants reduction transformation substances. We have investigated that are within frameworks, metals, molecular catalysts, catalyst single atom (SACs); reactive skeleton/linkages; pendant groups. This exploration aims benefits using COF‐based catalysts compared traditional catalysts. Despite new advantages, numerous difficulties also been noted regard future. The objective review is make it easier design composite materials practical uses.
