Ternary NiCo₂P<i>_x</i> Nanowires as pH‐Universal Electrocatalysts for Highly Efficient Hydrogen Evolution Reaction

Abstract

A bimetallic-structured ternary phosphide (NiCo₂ P_x ) as a novel pH-universal electrocatalyst for hydrogen evolution reaction is presented. It exhibits both high activity and long-term stability in all the tested alkaline, neutral, and acidic media. The excellent catalytic performance endows it with a bright future in the large-scale electrochemical water splitting industry.
