摘要	Photocatalytic disinfection is a promising way to combat bacterial pollution in the water environment. Inefficient use of visible light and undirected diffusion of reactive oxygen species (ROS) reduce photocatalytic disinfection efficiency. Herein, inspired by the concentrating effect of convex lens, photocatalysts with particular "nanomagnifying glass effect" (TCNMgNOs) were designed by embedding magnesium oxide with "converge effect" into the tailored hierarchical triple-shell porous g-C3N4 with "one light multi-purpose effect" to boost the visiblelight utilization. Meanwhile, the ATPase hydrolysis homeostasis of bacteria was destroyed by TCNMgNOs to achieve the targeted movement of ROS. The results confirmed that the photocatalytic sterilization efficiency of TCNMgNOs was amplified by 30 times over g-C3N4, which was achieved by focusing visible light, multiple reflecting visible light and light transmission within the porous thin shells as well as the "addictive sterilization mechanism". The sterilization efficiency still maintains 98.8 % (15 min) after 6 rounds recycling and reusing in practical river water disinfection. A novel pathway for fighting against microbial contaminants in natural water was explored.
