| 英文摘要 | Photocatalytic synthesis of H2O2 by carbon nitride photocatalyst under the conditions of air and pure water exhibits promising research potential with significant implications. However, carbon nitride faces impediments in photocatalytic reactions, such as overlapping redox active sites and poor charge dynamics (including slow exciton dissociation, inefficient surface charge extraction, rapid carrier recombination), which impede its efficient photocatalytic generation of H2O2. By modulating potassium doping behavior under the influence of methyl and cyano groups, we successfully induced the formation of lattice pathway. Through precise coupling of the crystalline-amorphous interface and the internal electric field generated by these functional groups, the lattice pathway is effectively integrated with the built-in electric field, thereby addressing the aforementioned challenges simultaneously rather than partially. This unique structure achieves a H2O2 yield up to 328.8 mu mol g-1 h-1 and a selectivity exceeding 91.5 % in both air and pure water. The DFT calculations and in-situ DRIFT were conducted to uncover that the interaction between functional groups and potassium atoms not only integrates oxygen reduction reaction and water oxidation reaction, but also induces alternating reaction sites of intermediates during H2O2 formation. This study highlights the significance of internal electric field and lattice pathway in optimizing the photocatalytic process and enhancing H2O2 production efficiency. |
