[en] Graphical abstract: - Highlights: • Co₃O₄/β-PbO₂ electrode was prepared and an excellent electrocatalytic property. • Co₃O₄/β-PbO₂ electrode had good corrosion resistance characterization and lifetime. • BPA electrocatalytic degradation followed pseudo-first-order reaction process. - Abstract: Ti-base Co₃O₄/β-PbO₂ 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 1.5 h electrolysis at NaCl concentration of 0.020 mol·L⁻¹, bisphenol A initial concentration of 20 mg·L⁻¹, applied voltage of 20 V, electrode spacing of 7 cm and electrolyte pH of 5. The reaction mechanism and kinetics of Co₃O₄/β-PbO₂/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
