摘要：To realize the double winning goal of environment and energy, a novel dual-functional photocatalytic reaction system is designed by using CO₂ conversion and pollutant oxidation in one cooperative system. S-scheme heterojunctions exhibit huge potential for accomplishing such synergetic coupling reaction system due to their strong redox ability and speedy charge separation rate. Howbeit, how to effectively adjust the charge transfer rate at nanometric heterointerface remains pivotal and challenging. Herein, interfacial Bi-N bond and N vacancy co-modulate Bi₁₂O₁₇Br₂/g-C₃N_4-x S-scheme junction is constructed, which not only presents superior separation and migration efficiency of charges, but also possesses high redox capacity. A series of theoretical and experimental results manifest that the synergistic effect of interfacial Bi-N bond and N vacancy availably expedite carrier transfer dynamics, achieving excellent photo-redox activity for cooperative CO₂ reduction and tetracycline oxidization. Furthermore, compared to two half-reactions, such elaborate cooperative reaction system displays an obviously elevated photo-redox activity. This work provides a deep insight into regulating interfacial charge migration of heterojunction by chemical bonds and defects.
