Electrochemical Behaviour of BaSn0.9Sb0.1O3 Coated Titanium Electrodes

Abstract

BaSno.9Sbo.1O3 /Ti electrodes were prepared by painting a slurry containing the oxide, synthesised by high-temperature solid state reaction, and Triton X-100 on titanium supports. The electrochemical behaviour of the electrodes was studied by cyclic voltammetry. From the voltammetric data the electrodes surface roughness was estimated and it was possible to conclude that an insulating film of TÍO2 is formed at the support/oxide layer interface.
