The selective catalytic reduction of nitric oxide with methane over La2O3-CaO systems: Synergistic effects and surface reactivity studies of NO, CH4, O2, and CO2 by transient techniques
(2000)Dispersing La2O3 crystallites in a 5 wt% La2O3-CaO mixed oxide system significantly enhances the intrinsic rate of NO reduction by CH4 in the presence of 5% O2 at 550°C compared to pure La2O3 and CaO phases. A synergistic ...

Synergistic effects of crystal phases and mixed valences in La-Sr-Ce-Fe-O mixed oxidic/perovskitic solids on their catalytic activity for the NO+CO reaction
(2000)Mixed oxidic and perovskite-type materials based on the La, Sr, Ce and Fe elements were prepared using a mixture of nitrates salts and heating at 1000°C. Three groups of solids were synthesized: (i) La(1-y)Ce(y)FeO3 (y=0.2, ...
