Abstract

Supported small and dense high-entropy-alloy nanoparticles (HEA-NPs) are promising functional materials for many applications. However, their synthesis remains a grand challenge because the extreme heating typically required to raise the entropic contribution to the formation of a solid solution unavoidably causes the sintering of HEA-NPs. Herein, we present a one-step continuous-flow spray pyrolysis strategy to synthesize multicomponent (from quinary to denary) HEA-NPs with an average size of
