    Abstract

    We synthesized a characteristic graphene-layered carbon particle composite using pyrolysis of hydrocarbon in an electric field and consecutive activation treatment under CO2 atmosphere. TEM, N2 adsorption isotherm, Raman spectroscopy, and XPS revealed structural features of this unique composite. Graphenes and carbon particles in the resultant composite are combined homogeneously in nanoscale with a mesoscale structure and with high carbon purity. When Pt nanoparticles are loaded on the composite, they show high performance as an electrocatalyst because of their higher electrochemical active surface area and higher durability against the sintering of Pt nanoparticles. Resulting material is a multifunctional composite by virtue of its nanostructural features.
