Regulating Relative Nitrogen Locations of Diazine Functionalized Covalent Organic Frameworks for Overall H 2 O 2 Photosynthesis
University of Shanghai for Science and Technology · Nanjing University
Abstract
Abstract Nitrogen‐heterocycle‐based covalent organic frameworks (COFs) are considered promising candidates for the overall photosynthesis of hydrogen peroxide (H 2 O 2 ). However, the effects of the relative nitrogen locations remain obscured and photocatalytic performances of COFs need to be further improved. Herein, a collection of COFs functionalized by various diazines including pyridazine, pyrimidine, and pyrazine have been judiciously designed and synthesized for photogeneration of H 2 O 2 without sacrificial agents. Compared with pyrimidine and pyrazine, pyridazine embedded in TpDz tends to stabilize endoperoxide intermediate species, leading toward the more efficient direct 2e ‐ oxygen reduction…
