Abstract: Provided is a catalyst including: a support including titanium oxide; an active catalyst component including vanadium oxide; and a co-catalyst including antimony and cerium, in which the catalyst is included in a deNox reduction reaction that decomposes nitrogen oxide. The catalyst may improve sulfur poisoning tolerance characteristics while improving the deNox efficiency at a temperature in a wide range from low temperature to high temperature.
