    摘要: Herein, we demonstrate a facile method for the introduction of nitrogen in the lattices of nickel nanoparticles to form NiNx (x = 0.13, 0.20, 0.27). X-ray absorption spectroscopy reveals the contraction of the Ni–Ni bond and modulated coordination environment after nitrogen introduction. The NiN0.20 required 87 mV overpotential for −10 mA cm−2 cathodic current density in simulated seawater. The density functional theory calculations revealed favorable EH2Oads and ΔGHads after N-introduction.
