摘要：

Different compositions of SnO2-TiO2 composite electrode coatings were prepared on conducting ITO glass substrates and photoelectrochemical measurements were carried out on the coated substrates under illumination with ultraviolet light. Photopotential as well as polarization measurements were made on the samples to evaluate their performance with regard to application for cathodic protection of metals against corrosion. A composite electrode bearing SnO2 and TiO2 in a 1:1 molar ratio was found to exhibit the maximum photocurrent and a maximum lowering of potential under illumination when compared to the other compositions. A possibility of using a pure SnO2 Coating for cathodic protection of metals against corrosion under dark conditions was also explored. (C) 2003 Elsevier B.V. All rights reserved.
