Abstract Strontium ferrates and cobaltates with compositions SrFeO3-δ (0.06⩽δ⩽0.40) and SrCoO3-δ (0.04⩽δ⩽0.30) were synthesized. The dependence of the oxygen electrode properties on the δ value was examined in 1 mol dm−3 KOH solution. In the SrFeO3-δ series, the samples with 0.24〈δ〈0.29, showed the highest activity in both oxygen evolution and reduction reactions. In contrast, no strong dependence on the δ value was observed in SrCoO3-δ, which also showed a high catalytic activity for oxygen evolution.
