| titleOfInvention | Preparation method of rare earth layered hydroxide nanosheet and sol thereof |
| abstract | The invention relates to a rare earth layered hydroxide nanosheet and a preparation method of sol thereof, wherein the preparation of the nanosheet comprises the following steps: preparing lanthanum nitrate solution with corresponding concentration, dissolving ammonium sulfate particles in the lanthanum nitrate solution according to a ratio to form mixed solution, adjusting the pH of the mixed solution to 6-10, continuously stirring to obtain uniform turbid liquid, reacting to obtain a product, immediately performing centrifugal separation and drying to obtain rare earth layered hydroxide La 2 (OH) 4 SO 4 ·nH 2 And (3) O nanosheet. And according to the proportion, placing the prepared nanosheets in a formamide solution, carrying out ultrasonic centrifugal treatment, and taking supernatant liquid to prepare corresponding nanosheet sol. The rare earth layered hydroxide La can be prepared by adopting an ice bath method to reduce activation energy 2 (OH) 4 SO 4 ·nH 2 The O nanosheet solves the problem that the compound in the prior art cannot adopt the traditional intercalation-stripping method to prepare the single-layer nanosheet, has simple process and convenient operation, can be produced in large scale, has good stability of corresponding nanosheet sol, and saves raw materials. |
