Ionic liquid intercalated V2O5 nanorods: synthesis and characterization

Abstract

Abstract. In this work, ionic liquid (IL) intercalated V 2 O 5 (IL-V 2 O 5 ) 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 V 2 O 5 . The Fourier transform infrared spectrum shows a band at 1044 cm -1 , which could be assigned to stretching vibration of terminal vanadyl (V=O), sensitive to cation intercalation between vanadium oxide layers. UV-vis absorption spectrum of IL-V 2 O 5 nanorods and calcined V 2 O 5 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 30-50 nm.
