Abstract: In one aspect, the invention relates to a method of synthesizing a nannoparticle/porous graphene composite, including dispersing porous graphene structures into a solvent to form a dispersion of the porous graphene structures therein, adding precursors of nanoparticles into the dispersion of the porous graphene structures in the solvent to form a precursor mixture, and treating the precursor mixture to form a nannoparticle/porous graphene composite. The composite is formed such that the nanoparticles are uniformly distributed in pores of the graphene structures. The composite is very useful as electrode materials in electrochemical devices, in which efficient ions and electron transports are required.
