Application No. 08/523,405
exemplary of the subject matter embraced by the claims on appeal:
1. A method for the desulfurization of
gases created by combustion of sulfur containing
hydrocarbons comprising the steps of providing microdomains
of cerium oxide on a substrate to form a cerium oxide-
substrate composition and exposing the microdomains of
cerium oxide to said gases, wherein said cerium oxide
constitutes at least 50 weight% of said cerium oxide-
substrate composition and said cerium oxide microdomains
react with the sulfur in said gases to reduce the sulfur
content of the effluent gas.
