• Electrochemical catalysis
• Ti/SnO(2)-Sb-Ce electrodes
• Electrocatalytic activity improvement
• Pollutant degradation

The antimony and cerium co-doped tin oxide (SnO(2)-Sb-Ce) films were successfully deposited on Ti substrates using ultrasonic spray pyrolysis (USP). The comparison of morphology and electrochemical properties between Ti/SnO(2)-Sb-Ce and Ti/SnO(2)-Sb electrodes was conducted. It was found that the Ti/SnO(2)-Sb-Ce electrodes had smaller sizes of coating grains, higher overpotential for oxygen evolution, and better electrocatalytic activity than the Ti/SnO(2)-Sb electrodes. The current efficiency was only 25% for degradation of 500 mg L(-1) Orange II on the Ti/SnO(2)-Sb electrode at a charge loading of 5.4 Ah L(-1), but increased to 47% on the Ti/SnO(2)-Sb-Ce electrode under the same conditions.
