▎ 摘  要

MoS2-reduced graphene oxide (MoS2-rGO: where rGO = 0, 1, 3, 5, 7 and 10 wt%) hybrids have been fabricated using (NH4)(2)MoS4 and graphite oxide as single source precursors of MoS2 and thermally exfoliated reduced graphene oxide respectively. These individual precursors were initially subjected to grinding for 30 min followed by heating at 1200 degrees C for 15 min and characterized. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and high resolution transmission electron microscopy (HRTEM) confirmed co-dispersion of MoS2 on thermally exfoliated graphite oxide. Electrochemical studies of these hybrids as anode materials showed that MoS2-rGO (7 wt%) exhibited superior reversible capacity, cycling stability, enhanced rate performance (780 mAhg(-1)) and rate capability (880 mAhg(-1)) over pristine MoS2 and other hybrids.
