摘要：

Rationally modulating the adsorption of reaction intermediates on the surface sites of carbon nitride-based catalysts could facilitate the photocatalytic reduction of O2 to H2O2. Herein, theoretical calculations reveal that multiple sites of heteroatoms and defects can synergistically increase local proton coverage and lower the kinetic barrier for O2 protonation, thereby promoting the production of *OOH and the subsequent generation of H2O2. As a proof of concept, carbon nitride (BPMC-Vs) with multiheteroatoms (B and P) and multidefects (N defects, -C equivalent to N) was successfully synthes...
