Embodiment 1

[0017] Embodiment 1: the method that adopts microwave irradiation method to synthesize zinc vanadate ultra-long nanowire material

[0018] At room temperature, the molar concentration of the zinc nitrate aqueous solution is 0.20 mol / L, and the solvent is 5 ml; the number of moles of ammonium metavanadate solid is 2 times of the number of moles of zinc nitrate, and hot distilled water at 60-75 °C is added and heated. Stir until the ammonium metavanadate is completely dissolved to obtain a homogeneous clear solution, then dropwise added to the zinc nitrate solution, vigorously stirred for 10 minutes; the above-mentioned reaction raw material mixture was poured into a round-bottomed flask, and placed in a microwave irradiation reactor ( The heating power of the equipment: 700W, the radiation frequency: 2450MHz) was reacted for 16 minutes, and the material prepared after the reaction was a zinc vanadate ultra-long nanowire material. The product was analyzed by SEM scanning electro...

Abstract

The invention relates to a method for synthesizing a vanadic acid zinc overlength nanowire material by microwave radiation. By using zinc nitrate and ammonium metavanadate as main raw materials and distilled water as solvent, a vanadic acid zinc one-dimensional nanometer material is prepared by the microwave radiation. The method is characterized in that the structure of a target product can be controlled by the method on a microcosmic scale, and the method is suitable for developing a minisize functional one-dimensional material excellent in performance. The method has the advantages that the method is high in operability of experimental conditions, low in energy consumption, and high in productivity and the like, the method for synthesizing the material can further provide basic researches of luminescent materials, electrochemistry, permanent magnet materials and biological medical materials with necessary theoretical basis and practical experience.

Description
