Abstract

Large-scale electrolysis of water for hydrogen production requires efficient and earth-abundant oxygen evolution catalysts. Here, we demonstrate a facile method to prepare catalytically active Mn₃O₄ octahedral crystals on Ni foam as a composite electrode, which exhibits outstanding activity and stability for electrocatalytic oxygen evolution.
