| Abstract: | Pure and strontium substituted lanthanum manganites were prepared by a sol-gel route and their electrocatalytic properties, in the form of film electrodes, were studied in relation to.O2 evolution. Results showed that the catalytic activity of new oxides in 1 M KOH at 25°C was 25-100 times higher than ones obtained by a conventional ceramic method. The Tafel slopes were ranging 90-114 mV decade and the reaction order in OH- concentration was found to be approximately one. Strontium substitutions have been observed to be greatly beneficial from electrocatalysis stand-point. |
