FENTON-LIKE CATALYTIC MATERIAL WITH DUAL -REACTIVE CENTERS AND PREPARATION METHOD THEREFOR

摘要

The present invention discloses a fenton-like catalytic material with dual reactive centers and a preparation method therefor. The method comprises the following steps: (1) placing a nitrogen-containing compound into a muffle for roasting, then dissolving the product into deionized water to form a turbid liquid solution; (2) dissolving aluminum nitrate nonahydrate, copper nitrate trihydrate and glucose into deionized water to form solution C; (3) adding the turbid liquid solution drop by drop into solution C, then performing airtight hydrothermal reaction and rinsing centrifugal drying to obtain a solid; (4) roasting the obtained solid in the muffle to obtain the fenton-like catalytic material. The catalytic material has a complete cone-shaped mesoporous structure with a large specific surface area, thereby exposing more catalytic active sites such that H₂O₂ can carry out reduction reaction in electron-rich center as much as possible to produce hydroxyl redials. The novel catalytic material can well remove various poisonous organic pollutants under neutral conditions, and can realize highselectivity conversion of H₂O₂.
