LaNi1-xFexO3 (x = 0, 0.25, 0.5) has been synthesized by the hydroxide solid solution precursor method for electrochemical characterization as oxygen anode in strongly alkaline medium. Studies were made at the oxide him, which was obtained by the oxide-slurry painting technique. The cyclic voltammetric study showed the formation of a diffusion-controlled quasireversible redox couple, Ni(II)/Ni(III), (E(0) similar to 430 +/- 10 mV) at the oxide surface in 1 M KOH. The reaction was observed to follow approximately first-order kinetics in OH- concentration. Values of the Tafel slope ranged between 59 and 86 mV decade(-1) with all the oxide film electrodes. The electrocatalytic activity was found to be greatest with the Ni/LaNi0.75Fe0.25O3 electrode. A comparison was made between the electrocatalytic activities of LaNiO3 prepared by the hydroxide solid solution precursor and by the hydroxide coprecipitation technique.
