Abstract

The invention discloses a preparation method of an organic anion pillared rare earth hydroxide nanosheet sol, the composition of the nanosheet sol is {Y1.9Eu0.05(OH)5(+)}-A, wherein A is benzoic acid radical, p-toluenesulfonic acid radical or dodecyl sulfate radical, the method takes yttrium nitrate hexahydrate, europium nitrate hexahydrate and sodium benzoate, sodium P toluenesulfonate or sodium dodecyl sulfate as raw materials, a hydro-thermal synthetic method is used for synthesizing a layered material of Y1.9Eu0.1(OH)5[A].2H2O; the layered material is treated by ultrasound in a n-butyl alcohol solvent to obtain the nanosheet sol which is peeled to a flaky state. The preparation method is simple and is environment friendly.

Description

technical field [0001] The invention relates to the technical field of chemical synthesis materials, in particular to an organic anion pillared rare earth hydroxide nanosheet sol {Y 1.9 Eu 0.05 (OH) 5 +}-A preparation method, wherein, A=benzoate, p-toluenesulfonate, dodecylsulfate. Background technique [0002] Layered compound is a spatial network structure formed by the accumulation of basic units of a certain structure by sharing corners, edges or faces. It is an important solid functional material. Due to its unique layered structure and interlayer chemical reactivity , so that it has broad application prospects in the fields of heat, mechanics, optics, electricity and magnetism, adsorption, conduction, separation and catalysis. Therefore, the research on layered compounds not only has very important basic theoretical academic value, but also has broad practical prospects. As a solid material, layered compounds have many modification methods: physical, chemical, mec...
