Problems solved by technology

But due to Fe 3 o 4 The basic Fenton reaction system mainly degrades organic pollutants in water through the catalytic reaction on the surface of the catalyst, and the nanoparticles are easy to agglomerate, so its degradation rate is lower than that of the traditional Fenton reaction under the same conditions.

Abstract

The invention relates to a nanometer Cu-Fe3O4@peanut shell carbon composite material as well as a preparation method and application thereof. According to the invention, peanut shells with the advantages of low price, wide source, environmentally friendliness and the like are selected for carbonization, so peanut shell carbon with the advantages of a certain porous structure, rich surface functional groups and the like is obtained; then the peanut shell carbon serves as a carrier, the nanometer Cu-Fe3O4@peanut shell carbon composite material with uniformly dispersed particles is synthesized insitu through a solvothermal method; and degradation tests show that the nanometer Cu-Fe3O4@peanut shell carbon composite material can be used for efficiently oxidizing and degrading rhodamine B dyes.The nanometer Cu-Fe3O4@peanut shell carbon composite material prepared by using the method has a series of the following advantages that the carrier is cheap, the in-situ growth and dispersion of nanometer Cu-Fe3O4 particles are facilitated, separation and recovery are easy, reusability is good, a pH value range required by heterogeneous Fenton reactions is wider, and the like.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a nano Cu-Fe 3 o 4 @peanut shell charcoal composite material and its preparation method and its application. Background technique [0002] Dye is an indispensable substance in life. With the continuous development of the economy, the types of dyes are increasing, and their structures are more complex, stable and not easy to be degraded. [0003] Untreated dye wastewater discharged from dye production and printing and dyeing industry has become one of the major sources of water pollution. This kind of wastewater not only affects the growth of aquatic organisms, but also has carcinogenic effects. It is difficult to effectively treat it with traditional water treatment methods. Therefore, the treatment of dye wastewater is imminent. [0004] Fenton oxidation technology is considered to be an effective technology for treating dye wastewater. With the deepening of res...
