Abstract

The invention relates to a ferric oxyhydroxide material modified by metal-doped cyclodextrin. The ferric oxyhydroxide material is a composite material formed by coating ferric oxyhydroxide and a metalion or metal with cyclodextrin, wherein the mass ratio of the cyclodextrin to the metal ion or metal to the ferric oxyhydroxide is 5-30: 0.1-10: 100; the ferric oxyhydroxide material is prepared by adding iron salt, metal salt and cyclodextrin to water and performing one-step reaction synthesis. The composite material provided by the invention greatly improves a catalysis effect of the ferric oxyhydroxide by doping of precious metals or transition metals and modification of cyclodextrin, not only has characteristics of hydrogen peroxide catalysis, photocatalysis, enzyme-like catalysis and thelike, but also has a host-guest inclusion effect of cyclodextrin supermolecules, and plays an important role in catalytic degradation of pesticide, physiological hormone and other types of pollutantsin water by the excellent catalysis performance and the inclusion effect of supermolecules.

Description

technical field

[0001] The invention relates to a metal-doped cyclodextrin-modified iron oxyhydroxide material and a one-step synthesis method thereof, belonging to the technical field of material synthesis. Background technique

[0002] Iron oxyhydroxide, as a natural mineral that widely exists on the earth's surface, is the main component of soil, sediment and water. They have stable physical and chemical properties and high specific surface area, and play an important role in pollutants in natural environmental media. It has gradually been paid attention to in the treatment of environmental pollution, especially iron oxyhydroxide nanomaterials have good characteristics as heterogeneous Fenton-like reaction catalysts. In addition, iron oxyhydroxide is also widely used in the fields of catalysis, industrial desulfurization, and synthesis of magnetic materials. The preparation and application of iron oxyhydroxide materials has become one of the most interesting and promisin...
