- Low-temperature de-NOx catalyst using ceria-alumina complex support and manufacturing method thereof

摘要

The present invention discloses a low-temperature nitrogen oxide removal catalyst using a ceria-alumina composite support and a method for preparing the same. According to the present invention, a ceria-alumina composite support synthesized by treating a ceria precursor and an alumina precursor by a co-precipitation method at a preset mass ratio is impregnated with a noble metal and a metal oxide. Low-temperature nitrogen oxide removal using a ceria-alumina composite support A catalyst is provided.
