Synthesis and Structural Analysis of Molybdenum Disulfide Nanoparticles by Sol-Gel Technique


Sundus S. Abrahaim and Ziad T. Khodair


Abstract: Sol-gel was used to make molybdenum disulfide nanoparticles (MoS2) for this work. X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), and Fourier transform infrared spectroscopy (FTIR) methods were used to examine the results. The XRD test showed that the nanoparticles were hexagonal, and the Scherrer method was used to find out that the average crystallite size (Dav) of the nanoparticles that were produced was around 40 nm. According to FESEM images, the crystalline forms are heterogeneous in size and shape, and the MoS2 nanosheets stack together to form a huge block with varying internal thicknesses. The average size distribution of MoS2 is about 42 nm. These results are consistent with the XRD. FTIR measurements performed for MoS2 nanoparticles showed that the strong and weak absorption bands of the (S - S) bond are located between (543-809) cm⁻¹, while the bands located (1100-1630) cm⁻¹ are due to the (Mo-S) bond, while the bands located at (2740-2357) cm⁻¹ are due to the (O-H) bond.

Keywords: Molybdenum Disulfide, Sol-Gel, XRD, FESEM, FTIR.
