Abstract

Morphology-controlled MoS₂ nanosheets were successfully synthesized with the aid of graphene/acid coexistence by a one-pot hydrothermal method. The ultrathin MoS₂ nanosheets were self-assembled into a cockscomb-like structure with an exposed (100) facet on graphene sheets, which is in strong contrast to large aggregate MoS₂ plates grown freely on graphene sheets without acetic acid. The ultrathin MoS₂ nanosheets displayed excellent rate performance for Li storage (709 mAh·g ^-1 capacity at 8320 mA·g^-1 discharging rate) and superior charge/discharge cyclability.
