Abstract

Atomically dispersed metal sites were immobilized on imine-pyridine based covalent organic frameworks to explore their novel applications in simulated sunlight-driven H₂O₂ production. Among them, Zn-COF_TAPB–BPA achieved a high H₂O₂ evolution rate of 2998 µmol g⁻¹ h⁻¹ and an apparent quantum yield (AQY) of 4.17% at 450 nm in pure water.
