Water oxidation is one of the most attractive techniques for intermittent renewable energy conver-sion and storage. The oxygen evolution electrocatalytic performance of an amorphous Co–B alloy and its derivatives were studied. These materials were chemically synthesized by reducing a Co salt with NaBH4. The amorphous Co–B alloy showed good electrocatalytic activity in oxygen evolution but its stability was poor. A hydrotalcite-wrapped Co–B alloy was synthesized by mild oxidation. The electrocatalytic activity of this material in the oxygen evolution reaction was better than that of a commercially available Ir/C catalyst.
