Studying the Mechanism of Catalytic Sonochemical Synthesis of Nanodispersed Molybdenum, Vanadium, and Tungsten Oxides by Dynamic Light Scattering
Abstract
The process of the ultrasound-induced nucleation and growing of the particles of hydratated molybdenum, vanadium, and tungsten oxides in the aqueous solutions of corresponding oxo-acids have been investigated using the dynamic light scattering technique. It has been shown that the sonoinduced polycondensation of oxo-anions is catalyzed by nickel and iron through the redox mechanism that permits one to generate monodispersed oxide particles with medium size that varies (depending on the ultrasound exposure dose) from 2 to 526 nm in the case of MoO3, from 15 to 664 nm in the case of V2O5, from 40 to 1098 nm for WO3.
