To enhanced photocatalytic activity and stability of titania (TiO2) coatings, graphene oxide (GO) forms on the surface of TiO2 coatings is fabricated by electrophoretic deposition (EPD). The results show the effect of EPD time on the formed hydroxyl groups from GO is significant, especially the controllable amount of GO by adjusting EPD time. The change in surface morphology of the GO on TiO2 coatings is obvious, showing an increased amount of GO. Owing to the effect of charge transfer between TiO2 and GO, the TiO2/GO composites coatings exhibit excellent and stable photocatalytic activity. Notably, the cycle result of the sample after ultrasonic cleaning every 10 min reveal that the combination of TiO2 and GO is satisfactory.
