“…Recently, boron-doped diamond (BDD) electrode has been attracted great attentions, especially for its particular properties including the wide potential window, low background current, high electrochemical stability and corrosion resistance [7][8][9]. BDD electrodes had been widely used as anodes for the degradation of refractory organic pollutants, such as nitrobenzene [10], salicylic acid [11], real textile effluent [12], dyestuff [13], perfluorinated compounds [14], sulfachloropyridazine [15], sulfanilic acid [16], methyl orange azo dye [17], real landfill leachate [18], and chlorophenoxy herbicides [19]. Meanwhile, reduction reaction simultaneously occurs at the cathode, resulting in generation of H 2 .…”
