Abstract

High-entropy alloy (HEA) nanoparticles offer unique catalytic properties due to their complex surface coordination and widely tunable electronic structures. Conventional synthesis methods typically involve extreme thermal shock (∼1700 °C) to achieve metal coreduction and mixing. While wet-chemical approaches hold potential for controlling nanoparticle properties, they are hindered by disparities in metal reduction kinetics and a diminished influence of configurational entropy on metal mixing at low temperatures, leading to phase segregation and limited compositional tunability. In this work, we introduce a novel wet-chemical hydrothermal method that enables the synthesis of HEA nanoparticles with enhanced…
