FeMoO4nanorod array: a highly active 3D anode for water oxidation under alkaline conditions

As a durable water oxidation electrocatalyst, an FeMoO₄nanorod array on nickel foam (FeMoO₄/NF) shows superior catalytic activity offering a geometrical catalytic current density of 50 mA cm⁻²at an overpotential of only 293 mV in 1.0 M KOH.
