Abstract Graphitic carbon nitride (gC 3 N 4 ) is an attractive photocatalyst for solar energy conversion due to its unique electronic structure and chemical stability. However, gC generally suffers from insufficient light absorption rapid compounding of photogenerated charges. The introduction defects atomic doping can optimize the improve carrier separation efficiency. Herein, high efficiency photocatalysis hydrogen evolution in visible achieved by S‐modified double‐deficient site strategy. Defect engineering forms abundant unsaturated sites cyano (─C≡N), which promotes strong interlayer C─N bonding interactions accelerates charge transport . S tunes semiconductors, formation C─S─C bonds optimizes electron‐transfer paths bonding, enhances light. Meanwhile,C≡N acts as electron trap capture photoexcited electrons, providing active reduction H + hydrogen. photocatalytic SDCN (1613.5 µmol g −1 h 31.5 times higher than that pristine MCN (51.2 ). situation transfer mechanism photocatalysts are investigated detail a combination experimental theoretical calculations.

Artificial photosynthesis for producing high-value hydrogen peroxide (H2O2) using carbon nitride-based systems holds immense potential. However, understanding the charge transfer dynamics in homojunction photocatalysts remains a significant challenge owing to limitations of current characterization techniques. Here, polymeric C3N5/C3N4 (CNHJ) is employed as model system probe interfacial electron transfer. Bimetallic cocatalysts serve sensitive probes, enabling situ tracking S-scheme between C3N5 and C3N4 via X-ray photoelectron spectroscopy. Leveraging unique advantages this S-scheme, CNHJ demonstrates substantially enhanced performance two-electron oxygen reduction reaction, achieving an impressive H2O2 production rate 8.78 mmol g-1 h-1 under visible light irradiation. Furthermore, robust continuous-flow setups, natural sunlight, photocatalytic disinfection tests, highlighting its practical This approach offers new insights into dynamic mechanisms paves way advancing artificial technologies.
