Realizing their potential : The title assay has enabled rapid screening of diverse mixed‐metal oxide electrocatalysts composed exclusively of earth‐abundant metal ions. Several newly discovered catalyst compositions (e.g., Ni/Al/Fe oxides) exhibit substantially lower overpotentials for water oxidation than known, widely used electrocatalysts.
