| titleOfInvention | Preparation method of three-dimensional self-assembled flower-shaped tungsten disulfide electrode material |
| abstract | A method for preparing three-dimensional self-assembly flower-shaped tungsten disulfide material comprises the steps of adding sodium tungstate dihydrate into a mixed solution of deionized water and ethanol, stirring until the sodium tungstate dihydrate is dissolved to form a transparent solution A, then adding ammonium acetate, stirring uniformly, adding oleic acid, mixing uniformly, adjusting the pH value1.3-1.7, carrying out hydrothermal reaction at 160-180 ℃ for 12-24 h, centrifuging, and drying to obtain WO 3 ·0.33H 2 O powder; according to a molar ratio of 1:20, adding WO 3 ·0.33H 2 And mixing the O powder with thioacetamide, and calcining to obtain the three-dimensional self-assembled flower-shaped tungsten disulfide material. According to the invention, oleic acid and ammonium acetate are added into an alcohol-water mixed system by using a hydrothermal synthesis method to control the nucleation growth of tungsten trioxide, the morphology is controlled, the synthesis method is simple and easy to control, the product dispersibility is good, and finally, the three-dimensional self-assembled flower-shaped WS is obtained by vulcanization 2 Uniform appearance, high purity and good application in the field of electrochemistry. |
