Abstract

Perovskite-type oxides have been considered for use as oxygen reduction and generation electrocatalysts in alkaline electrolytes. This paper is concern. Perovskite oxides have not been found, in general, to be very active for oxygen reduction, although substantial catalytic activity for hydrogen peroxid. A series of compounds of the type LaFexNi1-xO3 has been used as a model system to gain information on the possible relationships be. MES also shows that the introduction of Ni into the FE(III) matrix of LaFeO3 forces some of the FE(III) into the unusual FE(IV) state, while part o. The hydrogen peroxide decomposition rates have been found to undergo a substantial change in the range 0.25 < x < 0.5. A correlation has been f.
