Cu/Ba/bauxite possesses superior NOx storage and reduction (NSR) performances, high thermal stability, strong resistance against SO₂ poisoning and outstanding regeneration ability in comparison with Pt/Ba/Al₂O₃. It can serve as a cheap and promising alternative for traditional Pt/Ba/Al₂O₃ in NOx removal from lean-burn engines.
