Photocatalytic antibacterial: Nanomesh-structured g-C3N4 were prepared using SiO2 microspheres as template. The efficient contact with bacteria induced the prolonged capture and reaction time for killing bacteria. The porous structure promoted light absorption and realized more active edge. As a result, the photocatalytic antibacterial activity and the leakage of K+ ions was greatly enhanced via .OH radical as the main active species.
