Abstract

The invention provides an efficient synthetic method for a series of spinel nanostructured materials and relates to nanostructured materials. The efficient synthetic method comprises the steps that soluble salts of A and B are dissolved in an alcohol solvent and stirred, and a mixed solution is obtained, wherein A is one of Mg, Zn, Ni, Co, Ca and Cu, B is one of Al, Si, Cr, Bi, Fe and Ga, and the soluble salts adopt nitrates or chlorides; the mixed solution is transferred into an autoclave for a reaction, a precursor is obtained through centrifugation, and the series of spinel nanostructured materials can be obtained after calcination. The method has remarkable advantages in low-cost massive synthesis, and is wide in application range and suitable for synthesizing different kinds and morphologies of spinel and spinel-like nanomaterials, and product purity is high. Cheap and safe raw materials and simple synthesis steps are adopted, a reaction device is simple, and a reaction solvent can be recycled.

Description

technical field [0001] The invention relates to nanostructure materials, in particular to an efficient synthesis method of a series of spinel nanostructure materials. Background technique [0002] In recent years, spinel (AB 2 o 4 ) materials have attracted widespread attention in both academia and industry because of their excellent physical and chemical properties, including high melting point, high hardness, high mechanical strength, low thermal expansion coefficient, good thermal shock resistance, and chemical inertness. At present, spinel materials are widely used in refractory materials, high temperature infrared windows, humidity sensors, catalysis and so on. Spinel is a widely used functional material, but there are very few naturally occurring spinels, so it needs to be synthesized artificially to meet various application requirements. [0003] The most common method for artificially synthesizing spinel materials is to generate spinel materials in one step throug...
