Abstract

Graphical abstract: Highlights: Homogeneous hybridization of MoS2 and graphene can occur with exfoliated nanosheet precursors. Graphene oxide is more effective for hybridization with MoS2 than reduced graphene oxide. Mesoporous MoS2 -graphene nanohybrid shows excellent anode performance in Li-ion battery. Abstract: Mesoporous MoS2 –graphene nanohybrid with excellent electrode activity can be synthesized by the reductive hybridization of exfoliated MoS2 and graphene oxide (G-O) nanosheets under hydrothermal condition. The use of G-O precursor is crucial in synthesizing homogeneously hybridized MoS2 –graphene materials with mesoporous stacking structure. The MoS2 –graphene nanohybrid prepared with G-O shows promising electrode performance for lithium ion batteries with large discharge capacity of ∼1400 mA h g −1 for the 100th cycle and excellent rate performance, which is much superior to that of the homologue prepared with rG-O precursor and also restacked MoS2 nanosheets. The present results clearly demonstrate the usefulness of G-O precursor in the hydrothermal synthesis of graphene-based hybrid materials.
