Surfactant-Assisted Hydrothermal Synthesis and Characterization of Nano-Sized 2H-MoS2
Nano-sized molybdenum disulfide has been prepared by hydrothermal method via surfactant and ultrasonic assistance, using sodium molybdate and thiourea as reagents. The as-synthesized MoS2 samples were characterized by x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and transmission electron microscope (TEM); the effects of addition of CTAB on reaction process and resulted particles have been investigated in detail. It has been shown that the addition of CTAB can not only prevent the agglomeration of the particles, but regulate their morphologies and phase compositions. The resulting 2H-MoS2 with hexagonal phase and average size of 10-20nm can be directly obtained at low hydrothermal temperature needless of high-temperature sintering and inert gas protection.
