Synergic Regulation of Active Site Electron Polarization and Interlayer Electron Coupling in COFs for Photocatalytic Hydrogen Peroxide Synthesis.
Covalent organic frameworks (COFs) are promising photocatalysts for the oxygen reduction reaction (ORR), yet reconciling the different electronic requirements in different elementary steps remains challenging. Herein, guided by the Sabatier principle and Marcus-Hush electron-transfer theory, we report a PyaD COF with d...
