Preparation of the Novel Double-functional Composite Electrode and Its Role on the Degradation of Organic Pollutants in Water

Abstract

Abstract: 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 Vor 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.

Key words: Composite electrode, Carbon PTFE(air) O₂ electrode, TiO₂ photo-catalyst, Degradation, Aniline
