Abstract: A millimeter-scale peroxymonosulfate activator ZSM-5-(C@Fe) and a preparation method and an application thereof are provided. According to the method, a PMS activator ZSM-5-(C@Fe) with a millimeter-scale stable structure is synthesized in the following steps: (1) preprocessing a ZSM-5 by a carboxylation method to obtain a ZSM-5-COOH; (2) synthesizing a ferrous metal organic framework material by a thermal method to obtain a precursor Fe (II)-MOF-74; (3) dispersing the ZSM-5-COOH in the step (1) and an ethyldiol methacrylate in an acetonitrile, and mixing evenly to obtain a mixed solution; and adding the precursor Fe(II)-MOF-74 in the step (2) into the mixed solution, carrying out a stirring reaction under an action of an initiator, filtering to obtain a precipitate, washing, and drying in vacuum to obtain ZSM-5-MOFs; and (4) in a nitrogen atmosphere, heating the ZSM-5-MOFs in the step (3) to carry out high-temperature pyrolysis to obtain the millimeter-scale peroxymonosulfate activator ZSM-5-(C@Fe).

Abstract: The present invention discloses a copper-doped iron metal-organic framework, a preparation method thereof, and an application method for activation of persulfate to treat organic wastewater. The copper-doped iron metal-organic framework is prepared by solution impregnation method, using relatively large specific surface area and more hollow structures of the iron metal-organic framework to effectively load copper ion. This method uses the unsaturated-coordinate iron active center on the iron metal-organic framework and copper ions on the load as a catalyst body, utilizing catalytic synergies of both to efficiently and continuously activate persulfate to produce sulfate radical anion for degradation of organic pollutants. This method is suitable for various organic wastewater, with high catalytic activity, good durability, easy operation and easy recovery, and activation effect of this heterogeneous catalyst is still high even after being used repeatedly, having a great application prospect in degradation of organic pollutants in water.
