Abstract

Abstract H 2 O 2 is a significant chemical widely utilized in the environmental and industrial fields, with growing global demand. Without sacrificial agents, simultaneous photocatalyzed H 2 O 2 synthesis through the oxygen reduction reaction (ORR) and water oxidation reaction (WOR) dual channels from seawater is green and sustainable but still challenging. Herein, two novel thiophene‐containing covalent organic frameworks (TD‐COF and TT‐COF) were first constructed and served as catalysts for H 2 O 2 synthesis via indirect 2e − ORR and direct 2e − WOR channels. The photocatalytic H 2 O 2 production performance can be regulated by adjusting the N ‐heterocycle modules (pyridine and triazine) in COFs. Notably,…
