Carbon particles uniformly-supported carbon nanofiber composite material and application thereof

Abstract

The invention discloses a carbon particles uniformly-supported carbon nanofiber composite material. The composite material comprises polyimide-based carbon nanofibers and cyclodextrin-based carbon particles, and the cyclodextrin-based carbon nanoparticles are uniformly supported on the polyimide-based carbon nanofibers. The invention also discloses an application of the carbon particles uniformly-supported carbon nanofiber composite material. The composite nanocarbon material prepared in the invention has the advantages of simplicity in preparation, and high adsorption performance, has a higher specific surface area, richer pore structures and more adsorption sites than conventional carbon fibers, and has improved ability to remove micro-pollutant from water. The composite material has a stable fiber structure, can be recycled and reused, and has a good application prospect in the treatment of organic pollutants in water.

Description

technical field [0001] The invention relates to the technical field of carbon nanofiber composite materials, in particular to a carbon nanofiber composite material uniformly loaded with carbonaceous particles and an application thereof. Background technique [0002] The water quality problem has seriously threatened the survival and development of human beings. Generally, the organic pollutants in the water body are relatively small, but they have a huge toxic effect on human health. Such organic pollutants are extremely stable in chemical properties and cannot be degraded by the ecological environment. As they migrate in organisms and accumulate in the natural environment, they have serious impacts on the ecological environment and human health. There are many different methods for removing organic pollutants in water bodies, such as: biological treatment, advanced oxidation, electrochemical method, and adsorption method. Among them, the adsorption method is an economical,...

Problems solved by technology

However, electrospun polymer-based carbon fibers have some drawbacks

Generally, due to the limitation of porosity, carbon nanofibers contain a large number of microporous structures and less mesoporous structures, so they can only be used for the removal of small molecular pollutants, and the removal efficiency of macromolecular organic pollutants is not high.
