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.
