Abstract	A gas diffusion electrode (air electrode) with a high current efficiency of electro-synthesizing H$_{2}$O$_{2}$ using O$_{2}$ in air was prepared. The several systems with air electrode as cathode of electro-synthesizing H$_{2}$O$_{2}$ on the reaction spot for degrading aniline in aqueous—electro-Fenton system, photo-excitation electro-H$_{2}$O$_{2}$ system and photo-electro-Fenton system, were developed. The rates of decomposition of H$_{2}$O$_{2}$ and mineralization of aniline were experimentally measured respectively under different conditions, and the results indicated there has an excellent parallel relation between decomposition rate of H$_{2}$O$_{2}$ and mineralization rate of aniline. Especially, photo-electro-Fenton system, where H$_{2}$O$_{2}$ is decomposed the fastest, is the best system of oxidizing and degrading organic toxicants. Compared photo-electro-Fenton system with photo-Fenton system, important role is revealed in the interface of air electrode. In this paper, the mineralization mechanism of aniline in the photo-electro-Fenton system was also discussed.
