Abstract:
Platinum (Pt)-based high-entropy alloys (HEAs) can optimize catalytic properties through multi-element synergy, yet conventional synthesis requires harsh conditions such as high temperature/pressure or toxic solvents, limiting sustainable applications. Here, we report the synthesis of a mesoporous high-entropy alloy composed of Pt, Pd, Rh, Ru, Cu, Au, Se, and Mo using a micelle soft-templating method by electrochemical deposition. The effects of electrodeposition potentials on entropy changes and element content are explored. The typical eight-element HEA exhibits the highest entropy value (>1.95R) among reported mesoporous HEAs to date. The mesoporous architecture enhances active sites and mass transport, offering an eco-friendly platform for advanced catalytic materials in energy conversion and storage.
