Ti-base Co 3 O 4 /β-PbO 2 composite electrodes were prepared using electro-deposition and characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), cyclic voltammetry and the accelerated life testing, it indicated that the self-made electrode had high activity in electrolysis as well as excellent corrosion resistance and excellent catalytic performance. The results showed that the removal efficiency of COD Cr could be reached up to 92.2% after 1.5h electrolysis at NaCl concentration of 0.020 mol·L −1 , bisphenol A initial concentration of 20 mg·L −1 , applied voltage of 20V, electrode spacing of 7cm and electrolyte pH of 5. The reaction mechanism and kinetics of Co 3 O 4 /β-PbO 2 /Ti composite electrodes electro-catalytic degradation bisphenol A mainly caused by the OH radical attacking parent molecules and the degradation followed pseudo-first-order kinetics.
