are responsible for the redispersion. In the application of selective catalytic reduction of nitrogen oxide, the conversion of the redispersed catalyst is increased from 46.2% (the fresh catalyst) to as high as 98.0% under the same conditions. Furthermore, the redispersion methods are repeatable for catalysts synthesized by different methods in this work. The above result not only increases the catalytic performance of the as-prepared catalyst but is also in favor of waste-catalyst regeneration.
