Carbonyl-Site-Mediated Oxygen Reduction in Fluorenone-Based Covalent Organic Frameworks for Efficient Hydrogen Peroxide Photosynthesis.
Hydrogen peroxide (H2O2) photosynthesis from molecular oxygen and water offers a sustainable route for decentralized oxidant generation, yet elucidating the molecular-level active sites for oxygen activation in covalent organic frameworks (COFs) remains challenging. Herein, we report a fluorenone-containing COF, FO-Tp,...
