MnO2/C and Pd/C catalysts used for the MnO2- Pd/C gas-diffusion cathodes were prepared by redox, and characterized by transmission electronmicroscopy (TEM), X-ray photoelectron spectroscopy (XPS). The electrochemical degradation of phenol was surveyed in a diaphragm electrolysis system and a connected electrolysis system, feeding with air, making the most of four kinds of self-made gas-diffusion cathodes. It turns out the MnO2- Pd/C cathodes was better than other cathodes, and the degration efficiency reached 96.95% and 99.3% in two kinds of electrolysis systems, respectively, after reaction for 100min.
