The solar-powered photocatalytic oxygen reduction reaction is considered a promising alternative method for H2O2 production under mild conditions. However, the intrinsic competitive pathway grossly inhibits selectivity and final yield of accompanying loss photogenerated electrons during process. Herein, two-coordinate nitrogen (N2C) vacancy-rich g-C3N4 (DCN1.2) was developed by polymerization pyrolysis using bottom-up strategy. DCN1.2 with low-coordinated N2C-vacancy enabled an enhanced in wide pH range. optimized demonstrated 556.2 μmol·gcat–1·h–1 at = 10, which approximately 3 times higher than that pristine CN (202.7 μmol gcat–1·h–1). DFT calculations photochemical experimental results revealed N2C-vacancies induced asymmetric electron distribution DCN, thereby facilitating transfer promoting O2 adsorption/activation production. Additionally, EPR situ FTIR measurements indicated could produce via sequential two-step single-electron pathway, achieving efficient good selectivity. This study provides guidance rational design defect-engineering catalysts generation.
