Molecular Assembly Unlocks Dual-Defect Synergy in Carbon Nitride for Efficient H₂O₂ Photosynthesis.

ABSTRACT: While promising for photocatalytic hydrogen peroxide (H₂O₂) production, the performance of graphitic carbon nitride (g-C₃N₄) is curtailed by a central synthesis paradox: the mutually exclusive conditions required to simultaneously create its most effective dual active sites-nitrogen vacancies and cyano groups. Herein, this paradox is resolved with a molecular assembly-molten salt coupling strategy, a precise bottom-up approach enabling the one-step, synergistic creation of K-doped g-C₃N₄ with both defect types. This photocatalyst achieves an exceptional H₂O₂ production activity of 2.65 mmol·g^-1·h^-1, which is 6.2 and 3.0 times higher than that of pristine and physically-ground K-dop
