Abstract
An integrated filter material, a preparation method and an application. The filter material is composed of a commercial dust removal filter material and a catalyst that is grown on the filter material and that has a function of simultaneously decomposing nitrogen oxides and dioxins. In the preparation method, a precursor solution of manganese and cerium oxides is impregnated on the filter material, and manganese and cerium oxides are grown on the filter material by means of a chemical reaction; and vanadium oxychloride is used as a precursor of vanadium oxide and is impregnated on the filter material, reacts in water, and prepared by drying, hydrothermal and other processes. The composite filter material may remove three kinds of pollutants in flue gas at the same time, and the catalyst is firmly loaded and does not easily fall off.
