Abstract:
The hollow PtPdRhRuCoNi high-entropy alloy was synthesized via an oil-bath and subsequent etching. With a specific surface area 1.7 times larger than Pt black, it exhibits superior activity and stability in 1 M KOH electrolytes containing ethanol, ethylene glycol, or glycerol. These improvements originate from the synergistic effect between its unique hollow architecture, which provides abundant accessible active sites, and its multi-element composition, which optimizes the electronic structure and facilitates efficient electron transfer.

When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...
