▎ 摘　　要

NOVELTY - Reduced graphene oxide/manganese(IV) oxide nanocomposite comprises reduced graphene oxide flakes and manganese oxide nanoparticles distributed on the surface of the flakes. USE - Reduced graphene oxide/manganese(IV) oxide nanocomposite used for electrode . ADVANTAGE - The reduced graphene oxide/manganese(IV) oxide nanocomposite exhibits excellent electron mobility, high thermal conductivity and the ability to sustain extremely high densities of electric current to only cite a few, but produce only a single layer material and therefore they are mainly used for fundamental research. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing a graphene material/metal compound nanocomposite comprising flakes of a graphene material and a metal compound distributed on the surface of the flakes, which involves exfoliating graphite in an exfoliation electrolyte comprising an intercalant and a precursor which is an oxometallate, a polyoxometalate, a thiometallate, or a metal salt together with an acid.
