摘要：
A unique MoS2/RGO/MoS2 (MRMS) nanostructured composite is prepared on Mo net surface through an in-situ hydrothermal synthesis. During the synthesis process, Mo net serves as not only a support but also Mo source for the lower MoS2 layer and reductant of GO. MRMS samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FESEM) and Transmission electron microscopy (TEM). As-synthesized MoS2/RGO/MoS2@Modirectlyac-tedassupercapacitorelectrodewhichexhibitedexcellentelectrochemicalperformance(*): A high capacity of 1138.5 mF cm(-2) at 20 mA cm(-2) (455.3 Fg(-1)), and a capacity retention of 98.8% after 4000 running times. A symmetric supercapacitor device consisting of two MRMS electrodes was assembled, which exhibited an energy density of 6.22 Wh kg(-1) and power density of 1.87 kW kg(-1). (C) 2016 Elsevier Ltd.
