Rational design of benzodifuran-functionalized donor–acceptor covalent organic frameworks for photocatalytic hydrogen evolution from water

Abstract

A benzodifuran-based donor–acceptor covalent organic framework was synthesized and employed for efficient simulated sunlight-driven photocatalytic hydrogen evolution from water, which exhibited a superior and steady hydrogen evolution rate of 1390 μmol g⁻¹ h⁻¹ and an outstanding apparent quantum yield (AQY) of 7.8% was obtained at 420 nm.
