Development of highly efficient sulfur-doped TiO2 photocatalysts hybridized with graphitic carbon nitride

- Two kinds of powdery semiconductors, S-doped TiO2 and graphitic carbon nitride, were hybridized.
- Photocatalytic activity was evaluated by decomposition of acetaldehyde under visible light.
- The activity of the sample prepared by a planetary mill was 4-times higher than that of S-doped TiO2.
- The sample prepared by a planetary mill showed Z-scheme charge transfer under visible light.
