Size‐Adjustable High‐Entropy Alloy Nanoparticles as an Efficient Platform for Electrocatalysis

Abstract The high entropy alloy (HEA) possesses distinctive thermal stability and electronic characteristics, which exhibits substantial potential for diverse applications in electrocatalytic reactions. The nanosize of HEA also has a significant impact on its catalytic performance. However, accurately controlling nanosize and synthesizing small HEA nanomaterials remains a challenge, especially for the ultrasmall HEA nanoparticles. Herein, we firstly calculate and illustrate the impact of size on the electronic structure of HEA as well as the adsorption energies of crucial intermediates involved in typical electrocatalytic processes, such as the hydrogen evolution reaction (HER), oxygen reduction reaction…
