✦ Synopsis

The electrochemical characteristics of ternary-oxide electrodes with a general formula Ru p ,,Tips -,Sn,0, for chlorine evolution from 1 M NaCl solution were examined as a function of x by CV and ac impedance measurements. The morphologies of ternary-oxide electrodes were also investigated by SEM . The relationship between q• and C" was shown by the results to be linear . q', obtained by CV, and Cd, obtained by ac impedance could represent the electrochemically active surface area. Introducing SnO, into the electrodes improves the performance of the electrodes by increasing q' and Cd , and decreasing Ra . The morphology of the Ru-Ti-Sn ternary-oxide electrodes depended significantly on the content of SnO 2 . Among these electrodes, Ru o ,Ti o ,Sno ,O, gave the best performance .
