The Effect of Alcoholic Reducing Agent and CTAB on Morphology and Structure of VO₂ (M) Nano-Particles

Abstract:

M-phase vanadium dioxides (VO₂) is synthesized by hydrothermal-solvothermal method. In this process,V₂O₅ powder is used as raw materials,cetyltrimethylammonium bromide (CTAB) is used as templates and hydrazine combined with different alcohols such as 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(M) nano-particles were succsessfully synthesized under the conditions of thermal reduction temperature 250°C, reaction time 8h and drying temperature 60°C. The variety of alcoholic reducing agents plays an important role in the structure and morphology of the product VO₂(M). That makes the size of the particles smaller, and with the carbon atom numbers increasing, the crystallinity is better.The different methods of adding CTAB affect the polycrystalline structure of the product, which is VO₂(B) or VO₂(M).
