Tolerance and regeneration versus SO2 of Ba0.9A0.1Ti0.8Cu0.2O3 (A= Sr, Ca, Mg) LNT catalysts

In this paper, the tolerance and stability versus SO2 of Ba0.9A0.1Ti0.8Cu0.2O3 (A = Sr, Ca, Mg) perovskite-type catalysts for NOx storage application have been analyzed at 400 °C. Characterization results show that only strontium and magnesium are introduced into the perovskite structure. From those...
