Synthesis and characterization of NiMoO4 via ultrasonic route by a novel precursor

In this work, nickel molybdate (NiMoO4) nanostructures have been synthesized by low-temperature sonochemical method. Simplicity, rapid reaction rate, controllable reaction conditions and safety of the technique as well as the uniform shape, narrow size distribution, and high purity of prepared nano-sized materials are some of the main advantage of this method. The benefit of using ultrasound radiation in combination with thermal treatment is high yield and purity of product. The effect of various parameters such as: power of ultrasound irradiation, concentration of initial precursors, sonication time, and surfactant on morphology, size and purity of products were investigated. The products were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmittance electron microscopy, and photoluminescence spectroscopy. This work provides a general, simple and effective method to control the composition and morphology of NiMoO4 nanostructures.
