摘要：
The 2D-MoS2/rGO nanocomposite was synthesized hydrothermally using graphene oxide, sodium molybdate and thiourea as the reactants.The effect of hydrothermal temperature on structure and optical property of the MoS2/GO have been systematically investigated by FESEM, HRTEM, XRD, Raman, EDS, XPS and PL spectroscopy.The results indicated that the ultrathin MoS2 nanosheets with thickness in the range of ~6–13 nm (~6–8 layers) and average lateral size of ~130–330 nm were uniformly dispersed on the rGO surface.The estimated optical band gap for 2D-MoS2/rGO is achieved in the range of ~1.56–2.38 eV and it is found to be controlled by adjusting the synthesis temperature.
