Abstract

Mixtures of NiCo2O4 and FeO x were obtained by thermal decomposition of the nitrates of Ni, Co, and Fe in appropriate proportions. Two series of electrodes were prepared: (1) at constant composition (20 mol% FeO x ) and various calcination temperatures in the range 200 to 480 °C and (2) at constant calcination temperature (300 °C) and various compositions in the whole composition range 0 to 100 mol% FeO x . The oxide layers were characterized by thermogravimetric analysis, X-ray diffraction, scanning electron microscopy, and cyclic voltammetry. Experimental data showed that the layers consist of a mixture of phases in which Fe oxide is present as Fe2O3. The electrocatalytic properties were assessed by means of quasi-stationary potentiostatic current-potential curves for the O2 evolution reaction from alkaline solution. Results have shown that the mechanism of O2 evolution depends on composition moderately. The electrocatalytic activity appears to depend on composition only slightly.
