A facile synthetic route to NiPt3@NiS hetero-nanostructures 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 mAcm-2, which is substantially lower than Pt or NiS, synthesized through a similar approach and represents the most active hydro-gen evolution reaction (HER) electrocatalysts yet reported in alkaline solutions. NiPt3@NiS electrodes demonstrated an un-ceasing HER stability over eight days, which is well over those reported for Pt-based catalysts signifying capability of scaled hydrogen production.
