Abstract Nanowires of V{sub 2}O{sub 5} were prepared via hydrothermal route using NH{sub 4}VO{sub 3} as precursor in the presence of sulfuric acid at 120°C for 24 h. This synthesis process is free of any templates and reducing agents. Thermal analysis showed a phase change at 350°C and the samples were annealed at 500°C. The XRD analysis showed the monoclinic phase for the as-prepared and orthorhombic phase of V{sub 2}O{sub 5} when annealed at 500°C. Characteristic Raman peaks also expressed the same structural features. Microstructure analysis by SEM showed the nanowire structure of V{sub 2}O{sub 5} with thickness in the range of 20–50 nm and length in micrometers. The possible mechanisms of formation of the nanowires were schematically explained based on the layered structure of V{sub 2}O{sub 5}.
