2 nm bimetallic alloyed Au-Pt nanoparticles were synthesized via electron beam irradiation. The nanoparticles were characterized using TEM and EDAX analysis, and tested as electrocatalysts for different fuel-cell related reactions. Our results show that these Au-Pt nanoparticles are promising for application in fuel cells.
Radiolytic reduction of mixed AuIII/FeII ethylene glycol solutions led to two kinds of particles: 2 nm Fe rich nanoparticles as well as large rods (a few tens of nm) and faceted particles rich in gold and containing a small amount of iron. The adjunction of iron to gold enhances remarkably its electro-catalytic properties toward oxygen and proton reduction. Our results show that Au-Fe system is very...
