Abstract

The invention relates to a ferrite nanometer superstructure porous material and a method for preparing the same, in particular to a method for preparing a nickel ferrite, cobalt ferrite or zinc ferrite nanometer superstructure porous material. The preparation method comprises that: sodium oxalate is used as a precipitator, the soluble nickel, cobalt or zinc salt used as a raw material reacts with the soluble iron salt to prepare a precursor of oxalate, and the precursor is degraded by calcination at certain temperature to obtain the nickel ferrite, cobalt ferrite or zinc ferrite nanometer superstructure porous material. The nickel ferrite, cobalt ferrite or zinc ferrite nanometer superstructure porous material synthesized by the method has the advantages of high purity, uniform size, good dispersibility, mild reaction conditions, simple equipment, easily controlled process conditions and low cost, and meets the need of the actual production.

Description

technical field [0001] The invention relates to a ferrite nano superstructure porous material and a preparation method thereof, in particular to a preparation method of a nickel ferrite, cobalt ferrite and zinc ferrite nano superstructure porous material, belonging to the field of wet chemical manufacturing of nanomaterials. Background technique [0002] In recent years, ferrite materials have been widely used in practical applications. For example, nickel ferrite is not only a soft magnetic material, magnetic head material, moment magnetic material, and microwave magnetic material with excellent performance, but also a magnetostrictive material selected for the preparation of magnetoelectric conversion composite materials with excellent performance; iron with a spinel structure Cobaltate is also a widely used magnetic material; zinc ferrite is an important magnetic material and catalyst, and it is also a good desulfurizer. Ultrafine zinc ferrite particles are transparent in...
