Evaluation of stable catalytic anodes for oxygen evolution in sulphuric acid

The electrochemical activity and stability of Ti/(Ru02 -Ti02)/ (Ru02- Mn02) anodes have been characterised employing steady state, cyclic voltammetric and galvanostatic accelerated polarization techniques in 0.5M H2SO4. Their dependence on composition of Ru02-Mn02 has been highlighted based on the comparison of the data obtained by the above techniques. Attempt has also been made to derive 'Stability index' and 'Activity' from cyclic voltammetry data
