N2 - The development of efficient and inexpensive electrocatalysts is regarded as an urgent concern in electrochemical water-splitting system. Herein, we propose a novel strategy for the fabrication of molybdenum phosphide nanoparticles (MoP NPs) anchored on porous carbon cloth (MoP@PCC) as a noble metal–free electrocatalyst for hydrogen evolution reaction (HER). Benefiting from the thin and uniform coating of ultrafine molybdenum dioxide (MoO2) NPs on PCC, less-aggregated MoP NPs can be formed on PCC after thermal phosphidation, resulting in an efficient performance for HER over a wide pH range. Particularly, MoP@PCC exhibited good electrocatalytic activities in alkaline and neutral solutions with low overpotentials of 122 and 160 mV at a current density of −10 mA cm−2, respectively. Additionally, MoP@PCC exhibited long-term stability and durability with continuous 10,000 cyclic voltammetry (CV) cycles and chronopotentiometric operation over 50 h, both in alkaline and neutral solutions.
