▎ 摘　　要

NOVELTY - Graphene or platinum-gold nanocomposite manufacturing involves preparing graphene oxide colloidal solution, and platinum-gold nanocomposite colloidal solution. The prepared graphene oxide colloidal solution and platinum-gold nanocomposite colloidal solution are mixed to produce a mixed colloidal solution. The mixed colloidal solution is sprayed into aerosol droplets. The sprayed droplets are transferred into a heating furnace for thermally decomposition to obtain the graphene or platinum-gold nanocomposite. USE - Method for manufacturing graphene or platinum-gold nanocomposite used in three dimensional nano composite for direct methanol fuel cell (all claimed). ADVANTAGE - The method manufactures the graphene or platinum-gold nanocomposite in a simple and cost-effective manner with maintained super high surface area. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene or platinum-gold nanocomposite manufacturing method.
