Abstract
null null The state-of-the-art Ammonia Slip Catalyst (ASC) has a dual-layer washcoat architecture with a bottom layer of Pt/Al2O3 and a top layer of Cu/SSZ-13. A trade-off between the NH3 conversion and N2 selectivity presents a challenge in the ASC design. While a sufficiently thick and active zeolitic top layer increases the N2 selectivity, it also imposes a diffusion barrier to the reacting species in reaching the bottom Pt layer, lowering...
