Abstract: MoS2 uniform hierarchical microspheres were grown on a large scale by a simple hydrothermal method with the help of the surfactant tetrabutyl ammonium bromide (C16H36BrN). X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectrometer (FTIR), and thermogravimetric analysis (TGA) were used to characterize the products. The X-ray diffraction (XRD) pattern of the sample could be readily indexed to MoS2. SEM and TEM images showed that the as-prepared products were hollowed and constructed by nanosheets, with the diameter of about 2 μm and wall thickness of 100 nm. The possible formation mechanism of the flower-like structures was proposed on the experiment fact. The friction experiment was made at four-ball tribotester and it could be concluded that the base oil MoS2 macrostructures had better friction reduction than those with commercial MoS2. |
