High performance electrocatalyst for proton exchange membrane fule cell application

摘要

A method of manufacture of the composite of graphene and MWNT, wherein the strong electrostatic interaction between positively surface charged graphene and negatively surface charged MWNT enhances the interaction between 1D MWNT and 2D graphene which prevents the restacking of graphene and gives highly conducting and large surface area nanostructure; coating nitrogen containing polymers over (graphene + MWNT) hybrid structure to obtain a highly uniform and well controlled coating; and subsequent pyrolysis in inert gas atmosphere.
