文摘
- •
One pot hydrothermal method was adopted to prepare C-TiO2/g-C3N4 nanocomposite with high visible light photocatalytic activity.
- •
The mechanism was enhancement of visible light absorption and fast separation of electron-hole pairs.
- •
Interfacial charge transfer through C
Ti bond and NTi bond played a crucial role in separation of electron-hole pairs.- •
Active species h+,
O2−, OH were all generated in the photocatalytic process and O2− played a significantly important role.
