Abstract: A method for preparing a Fenton catalytic material includes the following steps: (1) placing a nitrogen-containing compound in a muffle furnace for calcination, then dissolving the product in deionized water to form a suspension solution; (2) dissolving aluminum nitrate nonahydrate, copper nitrate trihydrate and glucose in deionized water to form a solution; (3) adding the suspension solution in a dropwise manner to the solution, then performing a closed hydrothermal reaction, washing with water, centrifuging and drying to obtain a solid; and (4) placing the prepared solid in a muffle furnace for calcination to obtain the Fenton catalytic material. The catalytic material presents a complete ball-flower shaped mesoporous structure, has a large specific surface area and dual reaction centers to expose more catalytic active sites, so that H2O2 is reduced at the electron-rich center as much as possible to generate hydroxyl radicals during the reaction.

Abstract: The present invention discloses a mesoporous manganese ferrite Fenton-like catalyst and preparation method and application thereof and pertains to the field of preparation of Fenton-like catalysts. The present invention uses KIT-6 as a hard template agent to synthesize mesoporous manganese ferrite catalyst. The prepared mesoporous manganese ferrite and hydrogen peroxide constitute a Fenton-like system oxidation wastewater treatment system to carry out efficient removal and mineralization of organic pollutants in wastewater. The preparation method of the present invention is simple and efficient. The prepared Fenton-like catalyst has a mesoporous structure and a relatively large specific surface area.
