Visible light photocatalytic activities of nitrogen and platinum-doped TiO2: Synergistic effects of co-dopants

- Pt,N-TiO2 is the most active for both photocatalytic conversion and photocurrent generation.
- The systematic comparison among the photocatalytic kinetics, TAS, and the DFT was conducted.
- The synergistic effect is attributed to new mid-gap levels in which charge pairs are effectively separated.
