Abstract Internal electric fields (IEF) have been recognized as an efficacious driving force to improve the reactivity of photocatalysis. However, manageable modulation IEF in homojunction remains a great challenge. Herein, local phosphorization strategy by precisely controlling phosphorus (P) atom doping location is presented modulate orientation smartly high‐low crystalline carbon nitride (g‐C 3 N 4 ) homojunction. Different found guide different photocatalytic reaction paths. By incorporating P low‐crystalline g‐C (P‐LCN), modulated directing from P‐LCN high‐crystalline (HCN), which contributes S‐scheme mechanism over P‐LCN/HCN Conversely, HCN (P‐HCN) modulates LCN/P‐HCN reversing P‐HCN (LCN), and follows type‐II mechanism. Profiting effective photocarriers transfer separation dynamics, especially favored electrons reducing capacity, performs superior H 2 evolution (12.09 mmol·g −1 ·h than (4.53 ). Even 3% NaCl solution real seawater, still exhibits incredible production rates 8.45 4.61 , respectively. This study unravels modulating principle phosphorization‐dependent for first time opens potential enhancing efficiency

Enhanced photo-induced electron utilization leads to efficient photocatalytic hydrogen production. The inefficient separation of electron–hole pairs has hindered this process. This study introduces a synergistic approach using defect-rich SnS2 and Ti3C2 MXene as cocatalysts in two-step hydrothermal process address challenge. By integrating these materials with TiO2 nanosheets, we create novel composite, SnS2/Ti3C2/TiO2 (STT), that significantly boosts evolution. provides abundant active sites for generation, while facilitates charge separation. combination carrier diffusion enhances chromophore absorption, thereby increasing the overall hydrogen-production rate, achieving several grams per hour gram double molybdenum vacancies. Characterization techniques confirm phase composition composite (STT). Compared pristine other composites, STT optimized 150 °C treatment, shows H2-production rate nearly 192 times higher than pure 6 composites. presence vacancies further its specific activity evolution by suppressing recombination providing additional sites. Moreover, act dual cocatalysts, improving electronic conductivity electron-transfer efficiency. Our findings demonstrate potential combining develop highly sustainable photocatalysts been situ grown on conductive MXene, SnS2, rich vacancies, is uniformly distributed TiO2/Ti3C2 through method.
