摘要：
Photocatalytic water disinfection is a cutting-edge strategy for effectively sterilizing water in a cost-effective and environmentally friendly manner. A 2D/2D MoS2/g-C3N4 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-2 and H2O 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.
