Title:
PT-RU NANO-ALLOY/GRAPHENE CATALYST, PREPARATION METHOD AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/088678
Kind Code:
A1
Abstract:
A Pt-Ru nano-alloy/graphene catalyst comprises graphene as a support, and a Pt-Ru nano-alloy loaded on the graphene. The use of graphene as support for the catalyst takes advantage of the ion effect and two-dimensional ductility of graphene, which increases the stability of the catalyst. The catalyst is prepared by a reverse micelles system method which provides a micro-environment (i.e. water-in-oil microemulsion), so that the particle size of the resulting nano-alloy particles can be regulated easily and is more uniformly distributed. The use of the catalyst in electrochemistry is also disclosed.
