Embodiment
[0020] Example: A rapid precipitation preparation of two-dimensional BaMoO 4 method, including the following steps:
[0021] 1) At room temperature, 0.18MBa(NO 3 ) 2 and 0.14M (NH 4 ) 6 Mo 7 o 24 4H 2 O was dissolved in 15mL water respectively to prepare a mixed solution for subsequent use;
[0022] 2) Use a mixer to stir the mixed solution evenly at a rated speed of 300rpm until the mixed solution mixes and precipitates a large amount of visible white precipitate, which is ready for use;
[0023] 3) Wash the white precipitate in step 2 with water and ethanol, and then place it in an oven for drying at 60°C to obtain the high-purity two-dimensional nanomaterial BaMoO 4 (see attached Figure 1-2 ).
[0024] This method has many excellent characteristics such as high efficiency, rapidity and simplicity in the preparation of materials, overcomes the great challenge of regulating two-dimensional nanomaterials caused by the rapid crystallization of precipitation reactions...

The invention relates to the technical field of nanomaterial preparation and discloses a method for preparing two-dimensional BaMoO4 by fast precipitation. The method comprises the following steps: 1)0.18M of Ba(NO3)2 and 0.14M of (NH4)6Mo7O24.4H2O are dissolved in 15 ml of water respectively at room temperature, and a mixed solution is prepared for standby application; 2) the mixed solution is stirred uniformly by a mixer at the rated speed of 300 rpm until a large quantity of visible white precipitates are separated from the mixed solution for standby application; 3) the white precipitatesin step 2) are washed with water and ethanol and dried in a drying oven at 60 DEG C, and the high-purity two-dimensional nanomaterial BaMoO4 is obtained. The method for preparing two-dimensional BaMoO4 by fast precipitation is used for preparing the material with a liquid-phase room-temperature precipitation method, compared with the traditional sol-gel method and reverse micelle method, the method is low in cost, high in reaction rate, simple to operate, mild, easy to control, energy-saving and environmentally friendly, and the product has high purity and novel morphology.
