[en] 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@Mo directlyacted as super capacitor electrode which exhibited excellent electrochemical performance(*): A high capacity of 1138.5 mF cm⁻² at 20 mA cm⁻² (455.3 F g⁻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.
