MANGANESE OXIDE BASED CATALYST FOR DECOMPOSITION OF OZONE AND METHOD FOR PREPARING THE SAME USING POTASSIUM PERMANGANATE AS STARTING MATERIAL

摘要

PURPOSE: Provided is a manganese oxide based catalyst with uniform particle size distribution for the decomposition of residual ozone, and also a method for preparing the manganese oxide based catalyst using potassium permanganate as a starting material is provided. CONSTITUTION: The method comprises steps of (a) preparing an aqueous solution of potassium permanganate; (b) impregnating a carrier with the aqueous solution of the step (a); (c) separating the impregnated carrier from the aqueous solution and then drying it; and (d) firing the dried carrier.
