In this research, a hydrothermal method has been employed for synthesis of nanostructured MoS2 particles via the synthesis of MoO3. The structure of MoS2 samples was investigated by using a different precursors, such as DisodiumThiourea and Thioacetamide. Several investigation tools including FTIR, XRD, SEM, TEM, Raman and UV-Vis specteroscopy were used in order to characterize MoS2 nanostructures. XRD studies confirmed the hexagonal crystalline structure of samples. The FTIR spectra indicated the well-bonded MoS2 nanostructures. The size and the nearly uniform distribution of particles was detected by SEM and TEM. Photocatalytic activity of the MoS2 particles was checked by degration of Metylen Blue. Results showed the enhanced photocatalytic activity for the synthesized MoS2 with the molar ratio of 1:3 under UV irradiation.
