PT/GRAPHENE CATALYST, PREPARATION METHOD AND USE THEREOF

A Pt/graphene catalyst comprises graphene as carrier, and Pt loaded on the graphene. The use of graphene as carrier 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-particles can be regulated easily and is more uniformly distributed. The use of the catalyst in electrochemostry is also disclosed.
