Catalytic behavior of La-Sr-Ce-Fe-O mixed oxidic/perovskitic systems for the NO+CO and NO+CH4+O2 (lean-NOx) reactions
Belessi, Vassiliki C.; Costa, Costas N.; Bakas, Thomas V.; Anastasiadou, T.; Pomonis, Phillippos J.; Efstathiou, Angelos M. (2000)Mixed oxides of the general formula La0.5SrxCeyFeOz were prepared by using the nitrate method and characterized by XRD and Mossbauer techniques. The crystal phases detected were perovskites LaFeO3 and SrFeO3-x and oxides ...

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
Costa, Costas N.; Anastasiadou, T.; Efstathiou, Angelos M. (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 ...

Understanding the synergistic catalytic effect between la2O 3 and CaO for the CH4 Lean De-NOx reaction: Kinetic and mechanistic studies
Anastasiadou, T.; Loukatzikou, Loukia A.; Costa, Costas N.; Efstathiou, Angelos M. (2005)Doping of La2O3 crystallites with Ca2+ ions significantly enhances the intrinsic rate of NO reduction by CH4 in the presence of 5% O2 at 550°C compared to pure La 2O3 and CaO solids, while the opposite is true after doping ...
