Relative nitrogen locations of diazine rings on covalent organic frameworks (COFs) are finely tailored to maximize the photocatalytic performance for producing H2O2 with O2 and pure water. Benefiting from effective electron-hole separation, low charge transfer resistance, and reactive sites for the direct 2e oxygen reduction reaction (ORR) pathway, the pyridazine-based COF exhibits an excellent H2O2 production rate of 7327 μmol g−1 h−1.

调节二嗪功能化共价有机框架的相对氮位置以实现 H2O2 光合作用

共价有机骨架 (COF) 上二嗪环的相对氮位置经过精心设计,可最大限度地提高用 O 2和纯水生产 H 2 O 2的光催化性能。受益于有效的电子空穴分离、低电荷转移电阻以及直接2e -氧还原反应(ORR)途径的反应位点,哒嗪基COF表现出优异的H 2 O 2生产率,可达7327 μmol g -1  h −1
