Solvent effects on elemental distribution in HEA nanoparticle synthesis
CNM Menu
Scientific Achievement
Researchers revealed that the choice of solvent in polyol reduction synthesis of high entropy alloy (HEA) critically influences the spatial elemental distribution.
Significance and Impact
This study highlighted solvent selection’s importance in tailoring nanoparticle properties, offering a pathway to optimize catalytic performance for energy, chemical and environmental applications.
Research Details
- At the CNM, electron microscopy elemental mapping was used to show the surface composition of PdPtRhIrRu HEA nanoparticles.
- Electrochemical measurements at the CNM were carried out to provide information on reduction kinetics of metal salts in different solvents.
