Effect of Different Mineralizers in the Sonochemical Synthesis of Self-Assembled Nanorods Vanadium Oxide

Abstract

The effects of different potassium salts (KNO₃ and KCl) as mineralizer on the synthesis of self-assembled nanorods vanadium pentoxide, V₂O₅ via sonochemical treatment were studied at different duration i.e., 30, 60, 90 and 120 min. All the materials synthesized were further characterized by x-ray diffraction, scanning electron microscopy and transmission electron microscopy. X-ray diffraction patterns revealed that the potassium ion from the mineralizers reacted with the V₂O₅ after prolonged sonochemical treatment duration. The morphology of the V₂O₅ changed from platelet-like structures into nanorods after 90 min of sonochemical treatment. TEM micrographs show the process of formation of the self-assembled V₂O₅ nanorod bundles with increased sonochemical treatment duration.
