Abstract Electrochemical water splitting is considered to be one of the most potential strategies to achieve the hydrogen economy. In this paper, the porous NiMo alloys used as efficient electrocatalysts were designed and synthesized by microwave sintering powder metallurgy method. The as-prepared porous NiMo alloys as good electrocatalysts exhibit excellent hydrogen evolution reaction (HER) performance and outstanding durability in alkaline electrolyte (1.0M KOH). Especially, the porous Ni6Mo4 alloy shows smaller overpotential of 37mV at current density of 10mAcm−2 and a low Tafel slope of 82.1mV dec−1. The efficient electrocatalytic performance of Ni6Mo4 alloy can be attributed to the synergies of Ni, Mo and NiMo intermetallic compound, more active sites and quicker charge transfer rate.
