摘要：The hydrogen evolution reaction (HER) is of critical importance for sustainable hydrogen production from water electrolysis. In this work, we report a highly efficient and stable noble metal free HER catalyst, which is composed of homogeneously distributed metallic Ni and NiMo4N5 nanocrystals. The biphasic nanocrystalline Ni-Mo-N catalyst shows very low overpotential (53 mV in 0.5 M H2SO4 and 43 mV in 1 M KOH, at current density 20 mA/cm(2)) and good stability for HER in both acidic and alkaline electrolytes, which is a promising low cost alternative for platinum based HER catalysts.
