文摘
- •
Carbon quantum dots (CQDs) modified mesoporous TiO2 was made by sol-gel method.
- •
Remarkable visible light photocatalytic activity was observed for dye degradation.
- •
The composite material exhibits high stability and recyclability.
- •
The up-conversion properties of CQDs and mesoporosity of TiO2 were investigated.
- •
The dye degradation mechanism is illustrated.
