The methods for preparing the novel composite electrode, the double function of the novel composite electrode and the role of it on increasing the degradation rate of the organic pollutants (such as aniline) in water are introduced. The reaction mechanism is also discussed. The results indicate that when the working potential was controlled at 0. 05 V or so, the composite electrode made up of the carbon-PTFE (air) O2 electrode and the TiO2 photo-catalyst not only possesses photocurrent effect but also has a high efficiency of generating H2O2. Then the organic molecule in solution can obtain two kinds of roles on degradation coming from the combination of the photo-catalysis and the photochemical oxidation. The rate of degradation of the organic molecule is obviously enhanced.
