Pt–Ni octahedral nanocrystals as a class of highly active electrocatalysts toward the hydrogen evolution reaction in an alkaline electrolyte

Author affiliations

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.
