Abstract

Hexagon shaped h-MoO₃ nanorods have been fabricated via the probe sonication route using ammonium molybdate, urea and sodium dodecyl sulphate at 70 °C. Pure metastable h-MoO₃ and α-MoO₃ were obtained under the current synthetic conditions. The h-MoO₃ phase was transformed to α-MoO₃ phase at 400 °C, while the hexagon shape rods structures of h-MoO₃ were collapsed and transformed to elongated particles of α-MoO₃. As-prepared products were characterized by thermogravimetric analysis (TG), X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and high-resolution transmission electron microscopy (HR-TEM).
