Nanocomposite Synthesis of Nanodiamond and Molybdenum Disulfide

A chemically conjugated nanodiamond (ND)/MoS(2) nanocomposite was synthesized with amine-functionalized MoS(2) and acyl chloride-coordinated ND. The chemical structure and morphology of the nanocomposite were characterized to examine the dispersion of MoS(2) on the ND platform. The results revealed that the degree of dispersion was enhanced with increasing ratio of MoS(2) 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/MoS(2) nanocomposite was considerably greater than that of the MoS(2) electrode alone. Furthermore, the nanophase distribution of MoS(2) 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 MoS(2) electrode alone.
