| Abstract: | The ultrafine MoO3 was prepared using ammonium paramolybdate and nitric acid as raw materials,via chemical liquid phase reaction and adding different types of surfactants.The effects of adding different types of surfactants and adding different concentration of the same surfactant on the morphology of the ultrafine MoO3 were investigated.The structure and morphology were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results indicated that the disperse property of ionic surfactant was superior to cationic and non-ionic surfactants in the preparation of ultrafine MoO3 in the liquid phase,.Spherical ultrafine MoO3 with particle size of 100 nm could be prepared with DBS of 1.8 mmol/L could be synthesized. |
