Abstract

We have synthesized Pt-Ni octahedral nanocrystals with Ni(OH)₂ naturally formed on their surfaces as a promising catalyst for the hydrogen evolution reaction (HER) in an alkaline solution. For Pt-Ni octahedra of 9 nm in size, they exhibited specific and mass HER activities 15 times and 4.6 times greater than those of a commercial Pt/C catalyst in 0.1 M KOH solution.
