Covalent organic frameworks (COFs) have emerged as promising candidates for solar-driven photosynthesis of hydrogen peroxide (H2O2), yet the development high-performance COFs tailored practical applications presents substantial challenges. This research introduces integration redox-active catechol moiety into a series (TPE-COF-OH, TPB-COF-OH, and TPP-COF-OH), serving pivotal active site photocatalytic oxygen (O2) reduction to H2O2 through reversible catechol-quinone interconversion mechanism. process facilitates transformation o-benzoquinone in presence molecular O2, while photoexcited electrons are utilized revert catechol, reducing energy barrier synthesis. Notably, TPB-COF-OH demonstrates an unparalleled production rate 6608 μmol h–1 g–1, outperforming its counterpart, TPB-COF-OMe, which lacks unit. Furthermore, achieves solar-to-chemical conversion efficiency 0.84%, marking highest value among COF-based photocatalysts production. investigation not only underscores critical role engineering enhancing COF performance but also broadens horizon technologies.

Photocatalytic covalent organic frameworks (COFs) are typically constructed with rigid aromatic linkers for crystallinity and extended π-conjugation. However, the essential hydrophobicity of backbone can limit their performances in water-based photocatalytic reactions. Here, we first time report synthesis hydrophilic COFs aliphatic [tartaric acid dihydrazide (TAH) butanedioic dihydrazide] that function as efficient photocatalysts H
