Preparation Of Micro-nano Material Molybdate By Electrolytic Methods And Its Performance Research

Micro and nano materials because of its effect mesoscopic exhibit unique physical and chemical properties different from other materials, so as a pioneer in the development of materials science research synthesis of micro and nano materials is essential to further promote the use of the material.To explore the new method for the synthesis of the micro and nano materials has become an important research topic in the field of micro and nano materials. Molybdate micro nanoparticles have an important applications and value,due to their unique structure and properties in catalysis, optical, electromagnetic, sensors,and corrosion.However, synthetic methods molybdate micro nanoparticles have significant limitations, such as complex synthesis process requires high temperature and pressure and other harsh conditions, product purity is not enough, and uneven product ruler, irregular topography and other issues.Therefore, to explore a device simple, effective, easy to operate, mild reaction conditions, low cost and high yield, suitable for large-scale production of micro nanoparticle synthesis method has become an important issue.In this paper,we synthesis molybdate micro-nano particles of uniform morphology and size with the method of cation membrane electrolysis under ultrasound for the first time.At the same time, we have discussed the factors of different morphologies and characterized the substances synthesis in different conditions.The main contents of this thesis:1> With sodium molybdate (Na2Mo04) solution for the anolyte, zinc as the anode plate, hydrochloric acid as the cathode liquid, titanium network as the cathode plate, diaphragm electrolyzer with double room, not add any additives, electrolytic preparation of zinc molybdate under ultrasonic micro-nano particles.The structure and performance of the product particles were characterized by the X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet spectroscopy (UV), and fluorescence spectroscopy (PL) and other analytical techniques.The results showed that in different solution temperature, anolyte concentration, and the anode current density, the synthetic product is different, have different structure.The temperature and concentration have the greatest influence on the product and its structure. Under low temperature and low concentration, the formation of bar ZnMoO4·0.8H2O, while the diamond and flower spherical Na2Zn5(MoO4)6 are formed under high temperature and high concentration.the particle hair blue-violet light with the fluorescence spectroscopy (PL) test.2、With sodium molybdate (Na2MoO4) solution for the anolyte, different specifications of the brass strip as the anode plate, hydrochloric acid as the cathode liquid, titanium mesh as the cathode plate, diaphragm electrolyzer with double room, not add any additives, electrolytic preparation of copper molybdate nanoparticles.Molybdate under different conditions with different morphology attached on the copper plate, and formation of super hydrophobic materials after modification.the results showed that the electrolytic time has a great influence on the brass surface morphology.Electrolysis under the same time, different specifications of the brass shows the different appearance. With the reduction of zinc content in the brass, the formation of electrolytic copper molybdate nano lamellar structure is more uniform.After material modified with low surface,contact angle can reach 150° or more.
