Unraveling the Dual-Capture Strategy in Surface-Grafted −NH₂ on N-Defected g-C₃N₅ for Enhanced Photocatalytic Hydrogen Production

Industrial & Engineering Chemistry Research, Journal Year: 2024, Volume and Issue: 63(47), P. 20621 - 20632

Published: Nov. 14, 2024

N-rich carbon nitride (g-C3N5) became a promising photocatalyst due to its narrower band gap, larger π-conjugate network, and better visible light responsive hydrogen precipitation activity compared with g-C3N4. However, the inherent shortcomings still limited development of g-C3N5. To reasonably address this issue, N defects surface amino groups were successfully introduced into pristine g-C3N5 through facile one-step calcination. Systematical characterizations theoretical calculation confirmed that synergy surface-grafted group achieved dual-capture strategy, endowing higher hydrophilicity faster photogenerated carrier separation transfer efficiency. With modification urea, as-prepared samples exhibited specific area further provide more active sites during photocatalysis. The experimental results proved photocatalytic evolution (PHE) performance novel material was significantly enhanced, optimal reaching 5000.6 μmol·h–1·g–1, which 24.5 4.5 times than comparison sample, respectively. stability reusability N-defected verified by recycling tests without an obvious decrease after continuous 30 h irradiation. This work provided perspective insight for designing fabricating functionalized photocatalysts.
