The Effect of Alcoholic Reducing Agent on Morphology and Structure of VO2 (B) Nano-Particles
Vanadium dioxides (VO2) is synthesized by hydrothermal method. In this process,V2O5 powder is used as raw materials,cetyltrimethylammonium bromide (CTAB) is used as template and different alcohols such as methanol, ethanol, propanol and butanol are used as reductants. X-ray diffraction (XRD) and scanning electron microscopy (SEM) are used to test the properties of VO2 nanoparticles. The results show that VO2(B) nano-particles were succsessfully synthesized under the conditions of thermal reduction temperature 180°C, reaction time 24h and drying temperature 60°C. The variety of alcoholic reducing agents plays an important role in the structure and morphology of the product VO2(B), which relates closly to the electric properties of materials.
