Reaction network in the reduction of NOx species by CO over Pt-Ba/Al2O3 Lean NOx Trap catalytic systems

摘要：

Introduction Lean NOx Traps (LNTs) represent a viable solution for the abatement of NOx emissions from lean–burn engines 1. Several studies were published on the mechanisms of both the NOx storage 1 and reduction 2, but a complete understanding of these processes has not yet been achieved. In this study the reaction mechanism involved in the reduction of stored NOx when CO is used as reducing agent are analyzed, and the pathways originating the various reduction products (N2, NH3) are addressed.
