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.

Keywords: hydrogen evolution reaction; pH-universal electrocatalysts; ternary phosphide.
