DENTRATION CATALYST AND PRODUCTION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a denitration catalyst and a production method enabling to purify nitrogen oxides in exhaust gas at a lower temperature than that of a conventional catalyst. SOLUTION: The denitration catalyst is produced by co-precipitating vanadium oxide fine particles or vanadium solid solution fine particles containing a solid solution of molybdenum and/or tungsten formed into vanadium oxide as an activator on titanium oxide having an anatase-type structure as a carrier, and is deposited by 3-30 wt.% vanadium oxide on the carrier and has >100 m<2> /g specific surface area.
