In this work, a composite metal oxide electrocatalyst was developed to remove the organic pollutants through an electrochemical advanced oxidation process (E-AOP) while examining the effect of current density. Namely, Ti/Ti-V-Sn-Sb-oxide coated electrocatalyst was successfully prepared using dip coating method. The removal efficiency has been determined from the anodic oxidation treatment of 100 mL Methyl Orange (MO) azo dye solution in 0.05 mol L-1 Na2SO4 at pH 3 at different current densities of 10, 20, 30, 40 mA cm-2. The decolorization rate were about 96.45% for degrading 50 mg L-1 MO at the optimal current density of 30 mA/cm-2 and treatment duration of 60 min. The promising electrocatalytic performance of Ti/Ti-V-Sn-Sb-oxide electrocatalyst render the respective anode as a low-cost dimensionally stable anode (DSA) for decomposition of organic pollutants in the aqueous solution.
