A three-dimensional nickel nitride with reduced graphene oxide composite on nickel foam (s-X, where s represents Ni<sub>3</sub>N/rGO@NF and the annealing temperature X can be 320, 350, or 380) electrode has been fabricated through a facile method. We demonstrate that s-350 has excellent urea oxidation reaction (UOR) activity, with a demanded potential of 1.342 V to reach 10 mA/cm<sup>2</sup> and bears high hydrogen evolution reaction (HER) activity. It provides a low overpotential of 124 mV at 1 ...[more]
