Abstract
The invention relates to a composite material with a carbon layer loaded on the surface of an inorganic carrier. The composite material is characterized in that the material has the dual properties ofthe inorganic carrier and a carbon material, an inner core is the inorganic carrier, the surface is a coated carbon layer, and the carbon layer is controllable in morphology and thickness. The inorganic carrier may be a silicon-based carrier or a non-silicon-based carrier, and may be a non-porous material or a porous material. A carbon source is a biomass raw material such as glucose, sucrose, starch, cellulose and the like. The present invention also provides a preparation method of the composite material, which specifically comprises the following steps: (1) modifying an amino group on thesurface of the inorganic carrier by a silanization method; (2) taking the biomass as the carbon source, and loading the carbon layer on the surface of the inorganic carrier by a hydrothermal method; (3) roasting at high temperature to improve the graphitization property of the carbon layer The preparation process of the composite material is simple, convenient and low-cost, has a wide applicationrange, is easy to industrialize, and has broad application prospects in the fields of adsorption, chromatographic separation, battery materials and the like.
