In this paper, the characterization of cyclic voltammetry on SnO2/Ti anode in aniline solution is reported.It is found SnO2/Ti anode plays a wonderful electrocatalysic role on the electrochemical oxidation of aniline. With the improvement of cyclic numbers, the oxidation current decreased and reached a stable value in the end. The SnO2/Ti anode experienced a course of film growing. Finally, on the anode formed an organic stable black thin film. At this moment, the whole reaction was controlled by the properties of the film. The film properties is andalized.
