Abstract
Photocatalytic synthesis of hydrogen peroxide(H2O2)stands out as an economically viable and environmentally friendly approach for H2O2 production.Covalent Organic Frameworks(COFs)represent a class of crystalline non-metallic photocatalysts with well-defined chemical structures and easily tunable molecular and band structures,making them one of the most sought-after materials in recent years for H2O2 synthesis through photocatalysis.This review encapsulates the advancements in the field of COFs for photocatalytic H2O2 synthesis,focusing on aspects such as molecular structure design,bond modulation,active site engineering,and semiconductors hybrids.Finally,key challenges encountered by COFs in the photocatalytic production of H2O2 are highlighted,accompanied by recommendations for future developments in this domain.
