Nanocomposite Synthesis of Nanodiamond and Molybdenum Disulfide

A chemically conjugated nanodiamond (ND)/MoS₂ nanocomposite was synthesized with amine-functionalized MoS₂ and acyl chloride-coordinated ND. The chemical structure and morphology of the nanocomposite were characterized to examine the dispersion of MoS₂ on the ND platform. The results revealed that the degree of dispersion was enhanced with increasing ratio of MoS₂ nanosheets to ND. Moreover, the nanosheets consisted of several molecular interlayers that were well-dispersed on the ND platform, thereby forming a nanophase. The efficient electrocapacity of the ND/MoS₂ nanocomposite was considerably greater than that of the MoS₂ electrode alone. Furthermore, the nanophase distribution of MoS₂ on ND with a graphitic shell provided a large surface area and reduced the diffusion distance of ions and electrons. Therefore, the nanophase electrode showed higher electrochemical capacitance than that of the MoS₂ electrode alone.
