Influence of reaction temperature, time and molar ratio on hydrothermal synthesis of MoS2 nanosheets

MoS2 nanosheets (NS) were synthesized using a hydrothermal reaction between sodium molybdate and thiourea. The influence of various parameters like reaction temperature, time and molar ratio on hydrothermal synthesis is studied. It was found that the reaction temperature and molar ratio had a greater impact than reaction time. All these parameters influenced the structural and optical properties of MoS2 that were verified by various characterization techniques like X-ray Diffraction (XRD), UV-Visible (UV) spectroscopy and Photoluminescence (PL) spectroscopy. The thin film of the sample was formed by utilizing drop casting method and current voltage characteristics were measured to calculate the conductivity. The results reveal that optimization of the reaction is must before employing it for certain application and the work will further motivate researchers to utilize it in supercapacitors, Field Effect Transistors (FETs) and various optoelectronic applications.
