A New Process to Prepare Pt Alloy Nanoparticles

Pt alloy catalysts are potential candidates to replace pure Pt catalysts in fuel cells due to their higher activity. However, the activity and durability of the Pt alloys highly depend on the preparing method. The Pt alloys prepared by conventional impregnation method usually have large particle size, and element distribution in these particles is not...
