Photocatalytic water disinfection is a cutting-edge strategy for effectively sterilizing water in a cost-effective and environmentally friendly manner. A 2D/2D MoS/g-CN heterojunction photocatalyst was specifically designed to improve performance by enhancing the charge separation and reducing the photogenerated carrier loading rate. When exposed to visible light, electron and hole pairs generated on the surface of the heterojunction interacted with O and HO in the environment; this facilitated the production of exogenous reactive oxygen species (ROS) that effectively eliminated the bacteria. With this optimized structure, E. coli and S. aureus were completely inactivated in 20 and 30 min, respectively, under white LED irradiation.
光催化水消毒是一种前沿策略，能够以经济高效且环境友好的方式对水进行有效杀菌。一种二维/二维的MoS₂/g-C₃N₄异质结光催化剂经过专门设计，通过增强电荷分离和降低光生载流子负载率来提高性能。当暴露于可见光时，异质结表面产生的电子和空穴对与环境中的O₂和H₂O相互作用；这促进了外源性活性氧（ROS）的产生，从而有效消除细菌。凭借这种优化结构，在白色发光二极管照射下，大肠杆菌和金黄色葡萄球菌分别在20分钟和30分钟内被完全灭活。
