Herein, we introduce a La1−xSrxCoO3 perovskite catalyst, substituting for Pt containing LNT catalysts, to remove efficiently NOx from lean-burn engines. The NOx storage/reduction occurred alternatively on the perovskite in successive lean/rich atmospheres, and the NOx conversion reached 71.4% with 100% selectivity to N2 at 300 °C.
