Infectious diseases caused by bacteria intimidate the health of human beings all over the world. Although many avenues have been tried, various operating conditions limit their actual applications. Photocatalytic nanomaterials are becoming candidates to be competent for water purification. Here, a novel and more efficient S-scheme has been engineered between two dimensional (2D) layered phosphorus-doped graphitic carbon nitride (P-g-C N ) and BiOBr via hydrothermal polymerization to inhibit the recombination of charge and broaden light absorption. The as-prepared P-g-C N /BiOBr hybrids exhibits significantly improved photocatalytic disinfection contrast to g-C N /BiOBr in visible wavelengths, suggesting phosphorus doping which adjusts the band structure plays a significant role in the S-scheme system. And the sterilization rate of multidrug-resistant Acinetobacter baumannii 28 (AB 28) was 99.9999% within 80 min and Staphylococcus aureus (S. aureus) was 99.9%.
细菌性传染病威胁着全世界人类的健康。尽管已经尝试了许多途径，但各种操作条件限制了它们的实际应用。光催化纳米材料正成为胜任水净化的候选材料。在这里，通过水热聚合，在二维（2D）层状磷掺杂石墨相氮化碳（P-g-C3N4）和 BiOBr 之间构建了一种新颖且更有效的 S 型结构，以抑制电荷复合并拓宽光吸收。所制备的 P-g-C3N4/BiOBr 杂化物在可见光波长下表现出比 g-C3N4/BiOBr 显著提高的光催化杀菌效果，表明磷掺杂调节能带结构在 S 型体系中起着重要作用。并且耐多药鲍曼不动杆菌 28 株（AB 28）的杀菌率在 80 分钟内达到 99.9999%，金黄色葡萄球菌（S. aureus）达到 99.9%。
