Abstract
Nitrogen heterocyclic covalent organic frameworks offer great potential for H2O2 production due to their unique optical and electrical properties. Herein, we design four photocatalysts with varying nitrogen atom configurations to tune their electronic and energy-band structures. Among them, the covalent organic frameworks with pyrimidine achieves an efficient H2O2 production rate of 17014 μmol g−1 h−1 and a solar-to-chemical conversion efficiency of 1.84% in pure water without sacrificial agent or oxygen aeration. The theoretical calculation and experimental study confirm that it owns superior photoelectrochemical properties, oxygen reduction reaction activity, and the lowest reaction potential barrier,…
