A facile synthetic route to NiPt3@NiS heteronanostructures is reported, starting from a subsulfido bridged heterobimetallic nickel-platinum molecular precursor. Notably, the NiPt3@NiS on nickel foam displayed merely an overpotential of 12 mV at -10 mA cm(-2), which is substantially lower than that of Pt or NiS, synthesized through a similar approach and represents the most active hydrogen evolution reaction (HER) electrocatalysts yet reported in alkaline solutions. NiPt3@NiS electrodes demonstrated an unceasing HER stability over 8 days, which is well over those reported for Pt-based catalysts signifying a capability of scaled hydrogen production.
