Controllable synthesis of novel zinc molybdate rod-like nanostructures via simple surfactant-free precipitation route

摘要

Zinc molybdate rod-like nanostructures have been successfully synthesized by precipitation method process and using a solid organometallic molecular precursor [bis(salicylaldehyda-to)zinc(Ⅱ)], Zn(sal)_2, and (NH_4)_6MO_7O_(24)4H_2O as starting materials. Some parameters including time effect, temperature effect, and surfactant effect were investigated to reach the optimum conditions. The as synthesized nanostructures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmittance electron microscopy (TEM) and Fourier transform infrared (FT-IR) spectra. 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 zinc molybdate in aqueous solution, which will be important for inorganic synthesis methodology.
