Silver molybdate nanowires, nanorods and multipods like structures have been prepared by an organic free hydrothermal process using ammonium molybdate and silver nitrate solutions. The powder X-ray diffraction (PXRD) patterns reveal that the silver molybdate belongs to anorthic structure. The thickness, 200–500 nm, for silver molybdate nanorods/wires and 2–5 𝜇m for microrods are identified from SEM images. UV-visible spectrum of silver molybdate nanorods/nanowires shows maximum absorbance at 408 nm. Photoluminescence (PL) spectrum exhibits UV emission at 335 nm, violet emission at 408 nm and a weak green emission at 540 nm. The influence of hydrothermal synthesis conditions on silver molybdate nanowires, nanorods and multipods compositions were established.

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–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-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 30–50 nm.
