Abstract
A method of preparing a catalyst composition suitable for removing sulfur from a catalytic reduction system and the catalyst composition prepared by the method are provided. The method of preparation of a catalyst composition, comprises: combining a metal oxide precursor, a catalyst metal precursor and an alkali metal precursor in the presence of a templating agent; hydrolyzing and condensing to form an intermediate product that comprises metal oxide, alkali metal oxide, and catalyst metal; and calcining to form a templated amorphous metal oxide substrate having a plurality of pores wherein the alkali metal oxide and catalyst metal are dispersed in an intermixed form in the metal oxide substrate.
