Abstract EN
Cu/N codoped TiO2 films on Ti substrates were successfully prepared by electrochemical method with the goal of enhancing the photoelectrocatalytic activity under visible light.
The morphology and composition of the Cu/N codoped films were characterized using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), energy dispersive X-ray (EDX), and UV-Vis diffusion reflection spectroscopy (UV-Vis DRS).
The photocatalytic activities of the Cu/N codoped TiO2 films were evaluated by the degradation of humic acid.
The visible light photocatalytic degradation of humic acid (HA) was tested and Cu/N codoped TiO2 films showed the highest degradation efficiency up to 41.5% after 210 minutes of treatment.
It showed that Cu2+ and NH 4 + codoped TiO2 film significantly improved the photocatalytic efficiency under the visible light.
When +5.0 V anodic bias potential and visible light were simultaneously applied, the degradation efficiency of HA over the Cu/N codoped TiO2 films significantly improved to 93.5% after 210 minutes of treatment.
