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.
