Two-dimensional layered MoS2 nanosheets exhibit a wide
range of attractive properties and hold great promise in myriad fields.
However, the poor performance of surface functionality greatly limits their
applications. In this paper, we report on a facile approach to direct synthesis
of organic functional groups decorated MoS2 (OFGD-MoS2) nanosheets
based on the simultaneous exfoliation of bulk MoS2 crystal and
chemical conjugation of thiol ligands. The morphology and structure of OFGD-MoS2 nanosheets are
systematically characterized using microscopy (TEM, SEM, AFM), thermal
gravimetric analysis (TGA), and spectroscopy (Raman, FTIR, XPS) measurements. The content of attached functional groups can be controlled
simply by operating the experimental conditions. Furthermore, the
introduced functional groups show excellent structural stability and high
chemical reactivity, making them promising for further modification as
confirmed by the in situ growth of inorganic nanoparticles and polymers. In
addition, surface functionalized WS2 nanosheets can also be
synthesized by this approach. This investigation paves
the way for the synthesis and applications of advanced
MoS2-based materials.
