Exceptional alkaline hydrogen evolution by molybdenum-oxide-nitride-based electrocatalysts with fast water-dissociation and hydrogen-adsorption kinetics

We report a simple strategy for synthesizing Ni 0.2 Mo 0.8 N/MoO 2 nanorods on NF for exceptional HERs in alkaline media. The Ni 0.2 Mo 0.8 N/MoO 2 delivered an ultralow overpotential of 13 mV@10 mA cm −2 in 1.0 M KOH, which outperformed the benchmark Pt/C.
