Two prerequisites for the selection of alcohols as reductants with high efficiency for the selective catalytic reduction over Ag/Al2O3
Introduction The selective catalytic reduction of NOx (SCR) by alcohols over Ag/Al2O3 has received much attention as a potential method for removing NOx emissions from various oxygen-rich exhausts 1,2. To improve the overall performance of Ag/Al2O3 for NOx reduction, much effort has been devoted to gaining insight into the reaction mechanism. Nevertheless, many questions remain regarding the details of this multi-step process. To highlight this issue in the present study, methanol and butyl alcohol isomers were employed as reductants for the NOx reduction over Ag/Al2O3. A mechanism of the SCR of NOx by alcohols over Ag/Al2O3 was proposed, which provides an intrinsic criterion for the selection of reductants with high efficiency for NOx removal.
