Abstract

PURPOSE:To prevent lowering in activity of NOx reduction catalyst at the low temperature side in the presence of NH3 in supporting a sulfuric acid salt of Fe or FeV on an activated alumina carrier by impregnation method or co-precipitation method, by permitting H2O2 to be present during such preparation.
