An ultrathin CdS layer-modified MoO/NiS hierarchical nanoarray on Ni foam exhibits ultrahigh electrocatalytic activity towards the hydrogen evolution reaction with a small overpotential of 30 mV at -10 mA cm due to the synergistic effect of easy electron transfer among CdS, MoO and NiS/NF and the well-designed structure, which outperforms the current non-noble electrocatalysts.
泡沫镍上的超薄硫化镉层修饰的氧化钼/硫化镍分级纳米阵列，由于硫化镉、氧化钼和硫化镍/泡沫镍之间易于电子转移的协同效应以及精心设计的结构，在析氢反应中表现出超高的电催化活性，在-10 mA cm时过电位仅为30 mV，优于目前的非贵金属电催化剂。
