| Abstract: | SnO2 film is firstly prepared by plasma electrolytic oxidation technology in sodium stannate solution. The structure and photocatalytic property of the film are characterized by SEM, XRD and UV-Vis spectrophotometer. Rough and porous netlike film formed on the substrate. The XRD result showed the oxide was pure SnO2. The absorption edge of the film was determined as 420 nm. Photocatalytic degradation of rhodamine indicated SnO2 film was an effective photocatalyst. |
