We report that the oxygen evolution reaction activity of nickel foam can be enhanced remarkably via only simple immersion in  a ferric nitrate solution at room temperature. We demonstrate that the oxidation of the nickel foam surface by nitrate ions can increase the near-surface concentrations of OH− and Ni2+ ions, which results in the in situ deposition of a highly active amorphous Ni-Fe hydroxide layer.
