Resumo: In this paper the influence of calcination temperature on the corrosion resistance of a Ti/SnO2-Sb electrode prepared according to Pechini's method and its efficiency for phenol oxidation in chloride medium were investigated. When calcination was performed at 600 °C tin distribution throughout the film was more uniform, providing a more homogeneous film structure. Electrolysis of a 0.34 mol.L-1 NaCl solution containing 100 mg.L-1 phenol at 10 mA.cm-2 for 30 minutes lead to corrosion of the electrodes calcined at 400 and 500 °C, whereas the one calcined at 600 °C remained practically unchanged, indicating that the coating structure, which is dependent of calcination temperature, plays an important role on the structural integrity of electrode material. Phenol concentration was reduced in 90% with the Ti/SnO2-Sb electrode calcined at 600 °C after 60 minutes of electrolysis at 10 mA.cm-2.
