Abstract

An acanthosphere-like PtRuRhPdAuIr high-entropy alloy (HEA) was fabricated for the first time by the electrochemical method in a deep eutectic solvent. Owing to the HEA structure characteristics and the synergistic effect of multimetallic sites, the as-synthesized acanthosphere-like PtRuRhPdAuIr HEA exhibits outstanding electrocatalytic performance for the hydrogen evolution reaction in both acidic and alkaline electrolytes.
