Abstract

The invention provides a method for preparing a BiOCl monocrystalline nano-chip with a solvent heat method. The preparation is carried out in a stainless steel high-pressure reactor consisting of a polytetrafluoroethylene liner (with the volume of 45ml) and a stainless steel jacket. The preparation is realized by the following technological processes: (1) placing raw materials including BiCl3 (with the purity not smaller than 99.1wt%) and KBH4 (with the purity not smaller than 98.0wt%) into 20-30ml of a mixed solution of deionized water and absolute alcohol, and stirring for reaction, wherein the molar ratio of BiCl3 to KBH4 is 3 / 5, and the mixed volume ratio of the deionized water to the absolute alcohol is 1 / 4-1 / 3; (2) then, pouring the mixed solution with the filling amount of 4 / 9-2 / 3 into the polytetrafluoroethylene liner, sleeving the stainless steel jacket, placing into an environment with the temperature of 160-200 DEG C, and preserving the temperature for 16-24 hours; and (3) finally, cooling the high-pressure reactor to room temperature, collecting a reaction product, cleaning, separating, and finally collecting and drying to obtain a BiOCl monocrystalline nano-chip. The BiOCl monocrystalline nano-chip synthesized with the method has the advantages of good dispersity, thin thickness, uniformity in size distribution and good color, and can be widely applied to the fields of coating, inorganic pigments, high-quality cosmetics, pearlescent accessories and the like. The method has the advantages of low raw material price and simple process, and is easy for large-scale industrial production.
