摘要

The ultrasound-induced nucleation and growth of molybdenum, vanadium, and hydrated tungsten oxide particles in aqueous solutions of the corresponding oxo-acids have been studied by dynamic light scattering. The sono-induced polycondensation of oxo-anions can be catalyzed by nickel and iron through a redox mechanism, which permits the generation of medium-size monodispersed oxide particles varying in diameter from 2 to 526 nm for MoO3, 15 to 664 nm for V2O5, and from 40 to 1098 nm for WO3 depending on the ultrasound exposure dose.
