Lithium hexafluoride calcium aluminium material with hollow tetrakaidecahedron structure

Abstract

The invention discloses a multi-element fluoride material with a hollow tetrakaidecahedron structure. The multi-element fluoride material is prepared by adopting the following steps: stirring three metal nitrate solvents in deionized water so as to obtain a clear aqueous solution; adjusting the pH value of the solution by using dilute nitric acid and ammonia water to a certain value, then adding a fluoride solution, violently stirring for 10 minutes, finally transferring the mixture to a reaction kettle, heating the mixture for 2-4 hours at a certain temperature, collecting a product, and drying the product for 10 hours at the temperature of 80 DEG C. The multi-element fluoride material has internal pore diameters, thin crystal walls and enormous application prospect; the preparation technology is simple and is suitable for industrial production; the raw materials are inexpensive and easily available.

Description

technical field [0001] The invention belongs to the field of inorganic micro-nano materials, in particular to a lithium calcium aluminum hexafluoride material with a hollow tetradecahedron structure. Background technique [0002] Inorganic materials with a hollow structure with a high specific surface area have excellent performance and great application prospects in the fields of catalyst loading, drug sustained release, gas storage, and thermal insulation. The 21st century is the era of material science. With the rapid development of science and technology, traditional materials can no longer meet people's higher and higher requirements for material properties. Especially the physical and chemical properties of modern materials have attracted people's attention. This requires We can regulate the composition, structure, and morphology of materials at the molecular level, which provides a huge impetus for the basic research of new materials. When people synthesize inorganic...

Problems solved by technology

These methods must adopt appropriate methods to remove the template when obtaining inorganic materials with a hollow structure, such as hydrofluoric acid erosion, high temperature sintering, photocatalysis, etc. to decompose the template, but in the process of removing the template, it is easy because the material wall is too thin Insufficient mechanical strength leading to collapse of hollow structures
