Abstract

The invention discloses a copper and carbon composite hollow sphere particle material and a preparation method thereof, belonging to the technical field of composite powder preparation. The material is a hollow sphere formed by hydrothermal carbon and copper nano particles; a wall base body of the hollow sphere is the hydrothermal carbon; the copper nano particles are embedded in the hydrothermal carbon; the size of the hollow sphere is 40 nanometers to 50 microns; the size of the copper nano particles is 1-30 nanometers; and the wall thickness is 5-200 nanometers. The copper and carbon composite hollow sphere particle material is prepared by taking copper salt and a carbon source as raw materials, and taking trioctylamine as an additive, wherein the mole ratio of the copper salt to the carbon source is 0.01-5, and the mole ratio of the trioctylamine to the carbon source is 0.05-10. The preparation method comprises the following steps: placing mixing liquid into a hydrothermal reaction kettle; preserving the temperature for 0.5-60 hours at the temperature of 70-250 DEG C; taking the mixing liquid out of the reaction kettle; cooling the mixing liquid to room temperature; pouring the mixing liquid out and precipitating the mixing liquid; cleaning by distilled water and ethyl alcohol, so as to obtain the copper and carbon composite hollow sphere powder. The copper and carbon composite hollow sphere particle material and the preparation method thereof have the advantages that the process is simple, a template removing working procedure is saved in a hard template method, and the raw materials are environmental-friendly renewable carbon sources.

Description

technical field [0001] The invention belongs to the technical field of composite powder preparation, and in particular relates to a copper / carbon composite hollow spherical particle material and a preparation method thereof. Background technique [0002] Nanostructure is a new system constructed and built according to certain rules based on nanoscale material units. It includes one-dimensional, two-dimensional and three-dimensional systems, including stable clusters of nanoparticles and artificial superatoms, Nanotubes, nanorods, nanowires, and nanometer-sized holes. Nanostructure systems have become one of the research hotspots in the fields of physics, chemistry, and materials in recent years because they have both the characteristics of nanoparticles and the new effects caused by the combination of nanostructures. [0003] As a new nanostructure, hollow spheres can be used in many fields such as medicine, pharmacy, material science, dye industry, etc. They can also be us...
