Perovskites are cost-effective and efficient catalysts for electrocatalytic oxygen evolution, however often lack stability. Here, the authors report a tetravalent iron based quadruple perovskite which is both active and stable, due to the covalent bonding network incorporating many of its iron and copper ions.
