Claim:
1. A method of preparation of a catalyst composition, comprising: combining a metal oxide precursor, a catalyst metal precursor and a sulfur scavenger precursor in the presence of a templating agent to form a combination; hydrolyzing and condensing the combination so that the sulfur scavenger precursor is converted to a sulfur scavenger compound and the catalyst metal precursor is converted to a catalyst metal to form an intermediate product that comprises metal oxide, a sulfur scavenger compound and catalyst metal wherein the sulfur scavenger compound is comprised of an alkali metal cation; and calcining the intermediate product to form a templated amorphous metal oxide substrate having a plurality of pores wherein the sulfur scavenger compound and catalyst metal are dispersed in an intermixed form in the metal oxide substrate and wherein the sulfur scavenger compound comprises an alkali metal containing material wherein the sulfur scavenger compound is lithium hydroxide and/or lithium aluminum oxide.
