Abstract

High temperature electrocatalysts based on double perovskite cobaltites that are typically employed in proton ceramic fuel cells and electrolyzers are exploited here for room temperature water oxidation. The double perovskites are assessed by the RctCdl product and we show that their intrinsic catalytic activities exceed that of IrO2.
