Water Splitting: Porous Nickel–Iron Oxide as a Highly Efficient Electrocatalyst for Oxygen Evolution Reaction (Adv. Sci. 10/2015)

A porous Ni–Fe oxide is presented as an efficient water oxidation electrocatalyst by W. Zhang, R. Cao, and co-workers in article number 1500199. The catalyst is constructed by evaporation of an organic surfactant from the layered Ni–Fe material under mild thermal treatment. The low evaporation temperature preserves the high surface area of the material, and is also ideal for formation of the highly active Fe-incorporated NiO electrocatalyst.
