--- Manganese-Ceria-Tungsten-titania catalyst for removing NOx and preparing method of thereof

摘要

The present invention relates to a method for preparing a catalyst for removing manganese-ceria-tungsten-titania-based nitrogen oxides with improved adsorbing amount of a reducing agent, wherein the pH of the slurry to which an aqueous solution containing manganese precursor is added is adjusted to 1 to 3, followed by drying and calcining. The present invention relates to a method for preparing a catalyst, and to a catalyst prepared therefrom, wherein the catalyst has an adsorption characteristic for ammonia and nitrogen oxides, thereby exhibiting excellent nitrogen oxide removal efficiency even in a low temperature region of 200 ° C. or less. Can be.
