Boosting Electrocatalytic Hydrogen Evolution Activity with a NiPt3@NiS Heteronanostructure Evolved from a Molecular Nickel–Platinum Precursor

This is the authors' abstract. We don't add key points for this paper.

A facile synthetic route to NiPt 3 @NiS heteronanostructures is reported, starting from a subsulfido bridged heterobimetallic nickel–platinum molecular precursor. Notably, the NiPt 3 @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. NiPt 3 @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.
