Sacrificial‐Agent‐Triggered Mass Transfer Gating in Covalent Organic Framework for Hydrogen Peroxide Photocatalysis
Hebei University of Science and Technology · Hebei Chemical and Pharmaceutical College
Abstract
Abstract Covalent organic framework (COF) photocatalysts for H 2 O 2 production remain challenging by mass transport limitations and poor charge separation efficiency. Herein, a sacrificial agent‐triggered mass‐transfer gating (MTG) strategy is developed to reconfigure interfacial reaction for photocatalytic H 2 O 2 generation via synthesized benzothiazole‐COFs. This enables precise switching of the dominant photocatalytic mechanism between surface‐confined directional charge transfer pathways and diffusion‐dominated redox processes. Notably, benzyl alcohol (BA) enhances the mass transport and the catalytic site accessibility, scavenges photogenerated holes, and supplies protons for coupling reactions, thereby…
