Title:
METHOD FOR GENERATING DENITRATION CATALYST IN SITU ON FILTER MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/176543
Kind Code:
A1
Abstract:
Provided is a method for generating MnO2 denitration catalyst in situ on filter material, the method comprising: first modifying filter material via the oxidation autopolymerization reaction of dopamine to enable the surface thereof to be uniformly coated with one layer of poly-dopamine film substance rich in active groups such as phenolic hydroxyl groups and nitrogenous functional groups, allowing the fiber surface of originally inert polyphenylene sulfide filter material to be active; and then generating MnO2 catalyst in situ on the filter material surface coated with poly-dopamine through chelation of the poly-dopamine layer and a divalent manganese ion and utilizing potassium permanganate as an oxidizing agent, thus preparing a composite filter material having a denitration function. The method is simple, has low requirements on instruments and equipment, has no particular requirement of the type and shape of the substrate, has mild reaction conditions, has no environment pollution, and provides new thinking and method for the modification and denitration of filter material.
