New insight into the enhanced photocatalytic activity of N-, C- and S-doped ZnO photocatalysts

- N-, C- and S-doped ZnO investigated by DFT calculation.
- Stronger visible light absorption induced by both N and C doping.
- N-, C- and S-doped ZnO with lighter electrons and heavier holes.
- N, C and S doping facilitating separation of photogenerated charge carriers.
