▎ 摘　　要

Single and few-layers MoS2 were uniformly grown on the surface of chemically reduced graphene oxide (r-GO), via a facile liquid phase approach. The method is based on a simple functionalization of r-GO with oleyl amine which seems to affect significantly the MoS2 way of growth. Scanning-transmission-electron microscopy (STEM) analysis revealed the presence of single-layer MoS2 on the surface of a few-layers r-GO. This result was also con firmed by atomic-force microscopy (AFM) images. X-ray photoemission spectroscopy (XPS) and Raman spectroscopy were used for in-depth structural characterization. Furthermore, we have successfully applied the method to synthesize MoS2 nanocomposites with multi wall carbon nanotubes (CN) and carbon nano fibers (CNF). The results demonstrate clearly the selective MoS2 growth on both carbon-based supports.
