The carbon-PTFE O2 (air)-Fed cathode with a high current efficiency was prepared on which H2O2 was electro-generated by using O2 in air. It was used to degrade the organic toxic contaminants in the new type reaction system-electrochemical oxidation system, photo-excitation oxidant system and the photoelectro-Fenton system. The decomposition rate of H2O2 was measured in different systems under different conditions and was compared with the traditional system. The reaction rate of aniline to mineral was measured in the new type systems, and the results indicated the decomposition rate of H2O2 has an excellent parallel relation with the degradation rate of aniline, when the carbon-PTFE O2(air)-Fed worked in suit successively. Besides, the best system to degrade the organic molecule was the photoelectro-Fenton system, in which H2O2 was decomposed fastest. By comparing with photoelectro-Fenton system and photo-Fenton system, it reveals the important role of interface between the carbon-PTFE O2(air)-Fed cathode and solution in photoelectro-Fenton system. In this paper, we also discuss the mechanism of aniline to mineral in photoelectro-Fenton system.
