| Résumé : | TiO2/SnO2 and TiO2–SnO2 coatings were prepared on type 304 stainless steel by sol–gel method, respectively. TiO2/SnO2 coating is compared with TiO2–SnO2 coating in terms of energy storage ability and anti-corrosion property. The two coatings can be charged with reductive energy under UV irradiation in 3 wt% aqueous NaCl. The self-discharging time of the TiO2/SnO2 coating is slower than that of the TiO2–SnO2 coating. The slow discharging may be suitable for an anti-corrosion application for metal. In the case where TiO2/SnO2 coating electrode is electrochemically charged at −0.38 V (vs. SCE) for 1 h, it can maintain a good cathodic protection for type 304 stainless steel for 7 h in the dark, while the TiO2–SnO2 coating electrode can only maintain a good cathode protection for 0.5 h in the dark. |
