英文摘要	the feasibility of activated carbon fibers (acfs) used as a new type of particle electrodes in 3-dimensional (3d) electrode for the electrochemical degradation of phenol wastewater was investigated for the first time. the surface morphology, textual properties and electrochemical behaviors of acf were studied by scanning electron microscopy (sem), n-2-bet sorption and cyclic voltammograms (cvs), respectively. compared with the commercialized granular activated carbon (gac), acf particle electrodes exhibited higher electrochemical oxidation performance on the mineralization of target pollutant. the identification of intermediates indicated most of oxidation products were adsorbed onto the acfs. the detection of hydrogen peroxide and hydroxyl radicals in the reaction system suggested that the reaction mechanism was direct anodic oxidation of pollutant on acfs if the cathode did not contact the acfs. the operative parameters including initial concentration of substrate, applied current density and the initial aqueous ph have been scientifically studied in search of the optimum condition. based upon the obtained results, the acfs longevity was tested in solution at ph 2.0, revealing relatively high electrooxidation capacity and long catalyst lifetime of acfs in acid solution.
