Activity and Thermal Aging Stability of LaSrMnO (x = 0.0, 0.3, 0.5, 0.7) and Ir/LaSrMnO Catalysts for CO Oxidation with Excess O.

The catalytic oxidation of CO is probably the most investigated reaction in the literature, for decades, because of its extended environmental and fundamental importance. In this paper, the oxidation of CO on LaSrMnO perovskites (LSMx), either unloaded or loaded with dispersed Ir nanoparticles (Ir/LSMx), was studied in the temperature range 100-450 °C under excess O conditions (1% CO + 5% O). The perovskites, of the type LaSrMnO (x = 0.

Defect Chemistry and Chemical Looping Performance of LaMMnO (M = Sr, Ca, (x = 0-0.5)) Perovskites.

LaMMnO (M = Sr, Ca, (x = 0-0.5)) materials of the perovskite structure are synthesized by a co-precipitation method. They are subsequently investigated for their performance in a chemical looping process (fuel CH) using thermogravimetric analysis with simultaneous reaction.
