Abstract:
Efficient O2 capture and charge carrier separation are both essential for photocatalytic H2O2 production, yet simultaneously optimizing these processes remains challenging. Herein, we engineer a cationic microenvironment within a covalent organic framework to synergistically enhance O2 adsorption and directional charge migration, resulting in a three-fold enhancement in H2O2 yield compared to the non-ionic counterpart.
