This invention discloses a covalent organic framework-supported iron single-atom close-range coordination catalyst, its preparation method, and its application in the removal of phenol through activated PMS polymerization. By rationally designing the spatial configuration and rigid structure of the COF ligand using pyrazine and bipyridine, precise control of the Fe atomic spacing is achieved at the atomic scale, resulting in a catalytic center with both high stability and high activity. This significantly enhances the adsorption and electron transfer capabilities of PMS molecules, promoting the polymerization of phenol into a high-molecular-weight polymer and its precipitation separation. It not only removes the pollutant phenol but also achieves carbon resource retention and pollutant immobilization, realizing resource utilization. The catalyst preparation process does not require high-temperature pyrolysis, is mild, and can be scalable.

The utility model belongs to the technical field of fiber textile fabrics, and particularly relates to an anti-pilling fabric. By arranging the three-layer structure and additionally arranging the static electricity connecting fiber clusters connected with the static electricity generating fiber clusters on the anti-pilling layer, electrons on the surfaces of high-static-electricity materials such as regenerated fibers can be transferred, and the situation that short and small regenerated cellulose formed by breakage under the static electricity effect is separated from original plied yarn is avoided; the pilling phenomenon on the surface of the electrostatic generation fiber cluster is relieved. By arranging the static dispersing fiber clusters which are connected with the static connecting fiber clusters and are partially arranged outside the protective layer, static electricity can be transferred from the inside of the fabric to the outside along the electron generating end, the static electricity inside clothes is reduced, and meanwhile, the static electricity inside the clothes is reduced. The electronic divergence ends formed by winding and interweaving the electric divergence fiber clusters can also achieve the physical isolation effect between the surfaces of the fabric, friction between the electronic divergence ends and the protective layer is reduced, and the fuzzing and pilling problems are solved through static conduction and physical isolation.
