Document Type and Number:
WIPO Patent Application WO/2022/042530
Kind Code:
A1
Abstract:
Provided are an Mn2O3@N-doped porous carbon hybrid Fenton-like material, a preparation method therefor and an application thereof. The preparation method comprises the following steps: step one, adding manganese nitrate hexahydrate, trimesic acid and 2,2'-bipyridine into a hybrid solution of N,N-dimethylformamide and ethanol, and stirring; step two, transferring the mixture obtained in step one to a polytetrafluoroethylene-lined autoclave, and obtaining Mn-MOF solid material from closed hydrothermal reaction; step three, cleaning and drying the Mn-MOF solid material obtained in step two; and step four, obtaining a Fenton catalyst material through calcination of dried Mn-MOF solid material in a muffle furnace. The resulting material has a core-shell structure in which ultra-fine Mn 2 O 3 nanoparticles are uniformly distributed in a porous carbon layer structure, can effectively remove all kinds of organic toxic pollutants, especially phenol pollutants, under neutral conditions, and can achieve high-selectivity conversion of PMS.
