文摘
- •
TiO2 NTs electrode sensitized with copper NPs was prepared by SILAR technique.
- •
The rectifying behavior indicated the formation of Cu2O/CuO/TiO2 heterojunctions.
- •
Cu2O and CuO NPs enhanced the charge separation and the absorption of visible light.
- •
The effect of the amount of Cu2O and CuO on the PEC performance was investigated.
- •
The radical species involved in the PEC degradation of DCF were analyzed.
