Abstract

An ultrathin CdS layer-modified MoO₃/Ni₃S₂ 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^-2 due to the synergistic effect of easy electron transfer among CdS, MoO₃ and Ni₃S₂/NF and the well-designed structure, which outperforms the current non-noble electrocatalysts.
