Embodiment 1

[0028] Take 0.547g of zinc acetylacetonate and 1.466g of iron acetylacetonate into a 1L beaker, add 60mL of ethylene glycol monoethyl ether, stir and dissolve in a 50°C water bath. Then 30 mL of 30% (v / v) hydrogen peroxide was added, and the reaction was stirred for 1 h. After the sol was obtained, the sol was transferred to an oven at 120° C. for 24 h to dry. Calcined at 500°C for 4 hours to obtain ZnFe 2 o 4 -Composite materials of ZnO.

Embodiment 2

[0030] Take 0.547g of zinc acetylacetonate and 1.466g of iron acetylacetonate into a 1L beaker, add 60mL of ethylene glycol monoethyl ether, stir and dissolve in a 50°C water bath. Then 30 mL of 30% (v / v) hydrogen peroxide was added, and the reaction was stirred for 1 h. After the sol was obtained, the sol was transferred to an oven at 120° C. for 24 h to dry. Calcined at 900°C for 4 hours to obtain ZnFe 2 o 4 nano ferrite.

Abstract

The invention provides a ferrite/metal oxide material and a preparation method and application thereof. The ferrite/metal oxide material is a composite material of ferrite or ferrite-metal oxide, wherein the ferrite is of a spinel structure, a formula is MFe2O4, the metal oxide is one or more of Fe2O3 and metal M oxides, and M is one or more of Zn, Co, Mn, Cu and Ni. The preparation method comprises the steps that an iron precursor and a metal M precursor are dissolved in an organic solvent, and heating and stirring are performed; an aqueous hydrogen peroxide solution is added, stirring continues to obtain sol, and drying is performed under the condition of 120-150 DEG C; under a nitrogen or air atmosphere, calcination is performed at the temperature of 200-900 DEG C for 4-6 hours to obtain the ferrite/metal oxide material. The obtained product is small in particle size and controllable in composition, the preparation method is simple in process, and the ferrite/metal oxide material has a very good effect when serving as a catalyst to activate PMS and degrade organic pollutants in light-like fenton reaction and has an industrial application prospect.

Description

technical field [0001] The invention belongs to the field of metal oxide materials, and in particular relates to a ferrite / metal oxide material and a preparation method thereof, and its application in photo-Fenton reaction catalytic degradation of organic pollutants. Background technique [0002] As a kind of magnetic material, nanoferrite has attracted attention in recent decades due to its wide application in electronic equipment, information storage, magnetic resonance imaging, and drug delivery technology. In addition, it has the advantages of stable structure and easy magnetic separation, so it has application advantages in the field of catalysis for the degradation of pollutants in water treatment. [0003] There are many methods for preparing ferrite materials, such as high-energy ball milling, hydrothermal method, co-precipitation method, sol-gel method and so on. Although the traditional inorganic ceramic technology has been widely used, it has the disadvantages of...
