The Influence of the Hydrothermal Temperature on the Optical Absorption Properties and the Morphologies of MoO_3 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.
