Sonochemical synthesis and characterization of NiMoO4 nanorods

NiMoO4 nanorods have been successfully synthesized by sonochemical method process by using Ni(CH3COO)2·4H2O and (NH4)6Mo7O24·4H2O as starting materials. Some parameters including ultrasonic power, ultrasonic irradiation time, stirring effect, solvent effect, and surfactant effect were investigated to reach optimum condition. The as synthesized nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmittance electron microscopy (TEM), photoluminescence (PL) spectroscopy, Fourier transform infrared (FT-IR) spectra and energy dispersive X-ray microanalysis (EDX). Facile preparation and separation are important features of this route. This work has provided a general, simple, and effective method to control the composition and morphology of NiMoO4 in aqueous solution, which will be important for inorganic synthesis methodology.
