A systematic study on visible-light N-doped TiO2 photocatalyst obtained from ethylenediamine by sol-gel method

- N-doped titania with a higher N-doping level is prepared by a sol-gel method.
- Doping mechanism is explained by XRD, FT-IR and UV-visible absorption spectroscopy.
- Photocatalytic performance is evaluated by dye degradation and H2 evolution.
