摘要:A facile method to synthesize graphene-like MoS2 nanowall/graphene sheet (GL-MoS(2)nanowall/GNS) composites has been developed through a solvothermal method, and followed by annealing at 400 degrees C under Ar. The characterization results indicate that the thin flaky wall type GL-MoS2 nanowall was supported well on the crumpled graphene flakes with good dispersion. The as-obtained nanowall-nanosheet hybrids are more robust and still retain the reversible capacity of 700 mA h g(-1) after 100 cycles at a charge-discharge rate of 500 mA g(-1). The outstanding performance in electrochemistry is attributed to both the robust nanocomposite structure and the synergistic interactions between graphene and GL-M'oS(2) nanowall, which makes it an efficient stable lithium storage material.
