The Influence of the Hydrothermal Temperature on the Optical Absorption Properties and the Morphologies of MoO3 Submicrobelts
MoO3 submicrobelts with the radial direction of less than 500 nm were successfully synthesized with ammonium paramolybdate as molybdenum source and nitric acid as precipitant at 240 ℃ for 48 h with pH=3 using the hydrothermal method.The samples were characterized by X-ray diffraction (XRD),scanning electron microscope (SEM) and transmission electron microscope (TEM).XRD analysis shown that the phase of as-prepared samples was MoO3.SEM and TEM analysis confirmed that the slenderness ratio of MoO3 grows up with the increase of the reaction temperature.Ultraviolet-visible absorption spectroscopy (UV-VIS) results showed that MoO3 submicrobelts have the good optical absorption capacity.
