Abstract

Development of new catalysts for controlling nitrogen oxides $(NO_x)$ emissions is an important technical challenge as increasingly strict emission limits are being imposed. A new catalyst $Pd^{2+}$ substituted $CeO_2$ $(Ce_{0.98}Pd_{0.02}O_{2-\delta})$ was synthesized by solution combustion method. The material was characterized by XRD, TEM and XPS and used to investigate the reduction of NO by $H_2$. The catalyst shows 100 \% $N_2$ selectivity at low temperature and thus is superior to other catalysts reported in literature. A bifunctional reaction mechanism has been proposed to model the experimental data.
