ABSTRACT=<p>Single and few-layers MoS<sub>2</sub> 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 MoS<sub>2</sub> way of growth. Scanning-transmission-electron microscopy (STEM) analysis revealed the presence of single-layer MoS<sub>2</sub> on the surface of a few-layers r-GO. This result was also confirmed 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 MoS<sub>2</sub> nanocomposites with multi wall carbon nanotubes (CN) and carbon nanofibers (CNF). The results demonstrate clearly the selective MoS<sub>2</sub> growth on both carbon-based supports.</p>
