Abstract:
Since molybdenum disulfide (MoS2) nanoflakes possess unique thermal and optical properties, which are different from their bulk counterparts, they have attracted a lot of attention. In this work, three different samples of MoS2 nanoflakes, carbon nanopaticles and molybdenum disulfide/carbon nanocomposite (MoS2/C) were synthesized by one step hydrothermal method. The structural and optical properties of all samples were characterized by X-ray diffraction (XRD), Transmission electron microscopy (TEM), Raman spectroscopy, Fourier transform infrared (FTIR) and Ultraviolet-Visible (UV-Vis) spectroscopy. These characterizations confirm that carbon nanoparticles are placed between MoS2 nanoflakes successfully. The photothermal results of samples indicate that temperatures of carbon nanoparticles and MoS2 nanoflakes increase with irradiation of 808-nm continuous wave laser. But when composed together, MoS2/C nanocomposite produces higher photothermal heat than each individual sample. Photothermal experiment was also performed for different concentration of MoS2/C nanocomposite liquid solutions. The result shows that the amount of concentration of MoS2/C nanocomposite affects the produced heat.
