Efficient visible-light induced photocatalysis on nanoporous nitrogen-doped titanium dioxide catalysts

- The nanoporous N-TiO2 photocatalysts were successfully synthesized at room-temperature.
- The *N-TiO2 was irradiated with visible-light to improve the surface hydroxylation of the N-TiO2 surface.
- The N- and *N-TiO2 exhibited excellent photocatalytic and antibacterial activities.
- Moreover, the *N-TiO2 exhibits excellent photocatalytic stability.
