电化学磷化作为一种经济高效且环保的方法，首次提出制备部分覆盖有序多孔镍（p-Ni）表面的非晶态镍磷壳。与传统高温固相磷化工艺制备的Ni2P/p-Ni相比，所得Ni-P/p-Ni对析氢反应（HER）表现出优异的催化活性。 Ni-P/p-Ni 的这种增强的催化活性是由于非晶态 Ni-P 和邻近的含镍氢氧化物/氧化物的协同效应所产生的高固有活性所致。
Electrochemical-phosphorization as a cost-effective and ecofriendly approach is proposed to fabricate an amorphous Ni–P shell partially covering the surface of ordered porous Ni (p-Ni) for the first time. The obtained Ni–P/p-Ni shows superior catalytic activity for the hydrogen evolution reaction (HER), compared with the Ni2P/p-Ni prepared by a traditional solid-phosphorization process at high temperature. Such enhanced catalytic activity for the Ni–P/p-Ni is contributed to by the high intrinsic activity from a synergistic effect of amorphous Ni–P and the neighbouring nickel containing hydroxides/oxides.
