【 摘 要 】

In this work, ionic liquid (IL) intercalated V₂O₅ (IL-V₂O₅) nanorods have been synthesized through the IL-assisted hydrothermal method using imidazolium-based functionalized IL at 130°C for 3 days. The structure and morphology of the obtained product was characterized using various techniques. X-ray diffraction pattern reveals the intercalation of IL at 2𝜃 = 7° in orthorhombic V₂O₅. The Fourier transform infrared spectrum shows a band at 1044 cm^â€�??1, which could be assigned to stretching vibration of terminal vanadyl (V=O), sensitive to cation intercalation between vanadium oxide layers. UVâ€�?�vis absorption spectrum of IL-V₂O₅ nanorods and calcined V₂O₅ nanoparticles show a maximum absorbance at 402 and 420 nm, respectively. The morphology of the product was investigated by scanning electron microscopy and transition electron microscopy (TEM). TEM analysis reveals the nanorods with thickness of 30â€�??50 nm.
