Precipitation synthesis and characterization of cobalt molybdates nanostructures

CoMoO4 nanorods have been successfully synthesized by precipitation method using Co(C7H5O2)2⋅4H2O and (NH4)6Mo7O24⋅4H2O as starting materials. The effect of some parameters including reaction time, temperature, concentration, and surfactant 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 CoMoO4 in aqueous solution, which revealed potential new insight into inorganic synthesis methodology.
