Covalent Organic Frameworks for Photocatalytic Hydrogen Peroxide Generation

“… The design of novel photocatalysts requires a deeper understanding of the key properties of COFs that directly or indirectly govern the photocatalytic performance for H 2 O 2 generation.Recently, COFs have received considerable attention in the fields of organic synthesis, − water purification, pollutant degradation, − CO 2 reduction, − energy storage, − and water splitting. − After our first demonstration of COFs as semiconductor photocatalysts for the generation of H 2 O 2 , many efforts have been devoted to enhance the performance of photocatalytic H 2 O 2 generation using different strategies for the design of COF-based photocatalysts as well as the method of H 2 O 2 synthesis. ,,, To act as a promising photocatalyst, the COF must meet some essential features such as suitable band gap and band positions, strong visible light absorption, high crystallinity, efficient charge separation, photochemical stability and high porosity (Figure ).…”
