Sodium bismuth molybdate nanometer material and preparation method thereof

Abstract

The invention relates to a method for preparing a sodium bismuth molybdate nanometer material. The method comprises a step 1) of dissolving bismuth nitrate in ethylene glycol, and obtaining a bismuth-containing solution; a step 2) of dissolving sodium molybdate in ethylene glycol, and obtaining a molybdenum-containing solution; a step 3) of mixing the bismuth-containing solution obtained in the step 1) with the molybdenum-containing solution obtained in the step 2), and obtaining a mixed liquid; a step 4) of adding a mixture of ethanol and water into the mixed liquid in the step 3), performing uniform mixing and then transferring the mixed liquid into a hydrothermal reaction kettle for solvothermal reaction, and then performing filtration, washing and drying to obtain the sodium bismuth molybdate nanometer material. The ethylene glycol and the ethanol are taken as solvents, and bismuth nitrate and sodium molybdate are taken as raw materials to perform solvothermal reaction to prepare the sodium bismuth molybdate nanometer material through further reaction. A solvent is non-toxic and environmentally friendly, simple in process and mild in reaction condition, and the prepared sodium bismuth molybdate nanometer material is high in purity and has applications in multiple aspects.
