title: Template synthesis of hollow MoS2-carbon nanocomposites using microporous organic polymers and their lithium storage properties.
abstract: This work shows that hollow and microporous organic polymers (H-MOPs) are good templating materials for the synthesis of inorganic material-carbon nanocomposites. The precursor compound, (NH4)2MoS4, was incorporated into H-MOPs. Heat treatment under argon resulted in the formation of hollow MoS2-carbon nanocomposites (MSC). According to microscopic analysis, the MoS2 in the MSC has a layered structure with an elongated interlayer distance. The MSC showed high reversible discharge capacities up to 802 mA h g(-1) after 30 cycles and excellent rate performance for lithium ion batteries. The promising electrochemical performance of the MSC is attributed to the very thin and disordered nature of MoS2 in the carbon skeleton. The role of chemical components of the MSC in the electrochemical process was suggested.
