Role of Storage Material in NOX Storage and Reduction (NSR) and Three-Way Catalysts (TWC) During Cycling Operation
NOx storage and reduction (NSR) is a cyclic catalytic process that eliminates NOx from lean burn vehicles. There is an active debate about the NOx reduction mechanism, particularly at a high temperature and cycle frequency. Three-way catalysts (TWC) are widely applied in stoichiometric combustion …

Investigation of accelerated ageing protocols applied to Lean NOx Trap catalysts
… of a tri-metal (Pt-Pd-Rh) commercial Lean NOX Trap (LNT) catalyst. The investigation has been focused on the correlation between the real-world ageing and artificial or rapid-ageing procedures. Samples exposed to hydrothermal, vehicle and dynamometer ageing have been fully characterized, …

NOx Removal by LNT-SCR Dual-layer Catalysts
… emission standards have driven the progress of NOx storage and reduction (NSR) technology. NOx is stored in a lean NOx trap (LNT) catalyst during fuel-lean mode and reduced to N2 during fuel-rich mode. First, we investigated the impact of ceria on NSR in an Pt/Ce LNT catalyst. The physisorbed …
