MoS2/C composites were firstly prepared by hydrothermal method employing sodium molybdate, sulfocarbamide and glucose as starting materials. The graphene-like MoS2/a-C composites were obtained after annealing at 800 °C in H2/N2. The samples were characterized by XRD, SEM, EDS and HRTEM. It was confirmed that in the composites MoS2 has a structure of single-layer, which is named graphene-like nanostructure. The graphene-like MoS2 nanosheets were uniformly dispersed in amorphous carbon. The interlaminar distance of the adjacent graphene-like MoS2 nanosheets in the composites measured was ∼1.0 nm. The mechanism of the formation of the graphene-like MoS 2/a-C composites was investigated. The graphene-like MoS 2/a-C composites exhibited high capacity and excellent cyclic stability used as anode materials for Li-ion batteries. The composite prepared by adding 1.0 g of glucose in hydrothermal solution exhibited the highest reversible capacity (962 mAh g-1) and excellent cyclic stability. After 100 cycles, it still retained 912 mAh g-1. The significant improvements in the electrochemical properties of the graphene-like MoS 2/a-C composites could be attributed to the graphene-like structure of the MoS2 nanosheets and the synergistic effects of graphene-like MoS2 and amorphous carbon. © 2011 The Royal Society of Chemistry.||Source Title:||Journal of Materials Chemistry||URI:||http://scholarbank.nus.edu.sg/handle/10635/89035||ISSN:||09599428||DOI:||10.1039/c1jm10174a|
