Quinary RuRhPdPtAu high-entropy alloy as an efficient electrocatalyst for the hydrogen evolution reaction

Quinary RuRhPdPtAu high-entropy alloy nanoparticles (HEA-NPs) were prepared for the first time from a deep eutectic solvent by an electrochemical method. Owing to the benefits of high entropy and abundant surface active sites, the RuRhPdPtAu HEA-NPs exhibit outstanding electrocatalytic performance for the hydrogen evolution reaction. Quinary RuRhPdPtAu high-entropy alloy nanoparticles (HEA-NPs) are synthesized from a choline chloride-urea-based deep eutectic solvent, and exhibit excellent electrocatalytic hydrogen evolution reaction with low overpotential and Tafel slope.
