摘要
An environment-friendly carbon material with an atomic layer of graphene oxide (G0) graphene and an atomic layer of GO, hereafter denoted as GO-G-GO, was fabricated by an easy one-step hydrothermal method. GO-G-GO was obtained by centrifugation to separate GO and graphite from the remainder of products of a modified Hummers method by which GO was produced. A composite of our new material with MnO2 was also prepared. The structure, composition, and electrochemical properties of MnO2/reduced GO-G-GO composites and GO G GO were investigated by XRD, CV, SEM, and galvanostatic charge discharge curves. MnO2/RFLG composites (62.4wt% MnO2) exhibited a high specific capacitance of 140 F/g in 1 M Na2SO4 at a current density of 1 A/g after 1000 cycles.
