Method for preparing two-dimensional BaMoO4 by fast precipitation

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a rapid precipitation preparation of two-dimensional BaMoO 4 Methods. Background technique [0002] BaMoO 4 It belongs to metal molybdate, because of its special crystal structure, this substance has a wide range of potential applications in optics, energy storage and other fields.
