Abstract

CeO₂ nanoparticles/graphene nanocomposite is fabricated by depositing CeO₂ nanoparticles onto three-dimensional graphene material and its supercapacitor performance is further investigated. The nanocomposite shows a high specific capacitance and power density, demonstrating a strong synergistic effect possibly contributed from improved conductivity of CeO₂ and better utilization of graphene.
