Abstract

The invention discloses a preparation method for a core-shell carbon-coated iron nanocomposite material, and solves the problems of long preparation period, complex process, high raw material requirement and difficult product separation of a preparation method for preparing a carbon-coated metal nanocomposite material in the prior art. The preparation method comprises the following steps: 1) dissolving ferrocene in an organic solvent carbon source, uniformly mixing, and then adding a discharge medium to obtain a mixture; 2) carrying out microwave heating reaction on the mixture obtained in the step 1), and continuously charging an inert gas during the reaction process; and 3) after the reaction is concluded, continuing to charge the inert gas for a set time, cooling, and then eliminating the discharge medium to obtain the core-shell carbon-coated iron nanocomposite material.

Description

technical field [0001] The invention belongs to the field of composite material synthesis and functional material preparation, and in particular relates to a preparation method of a core-shell carbon-coated iron nanocomposite material. Background technique [0002] Carbon-coated metal nanocomposites are a new type of functional material, which has a unique core-shell structure and excellent physical and chemical properties. It is a research hotspot in the field of carbon nanocomposites today. The existence of the carbon coating layer can not only overcome the shortcoming that the metal nanoparticles cannot exist stably in the environment, but also effectively separate the metal nanoparticles from each other, thereby avoiding the mutual influence between the metal nanoparticles and greatly expanding the carbon coating. Application of metal-clad nanocomposites in magnetic materials, battery technology, catalysts, energy storage conversion, environmental protection, biomedicine...
