The CH4/NO/O2 "lean-deNOx" reaction on mesoporous Mn-based mixed oxides
Stathopoulos, Vassilis N.; Costa, Costas N.; Pomonis, Phillippos J.; Efstathiou, Angelos M. (2001)High surface area Mn-based porous oxides (MANPO) containing additives like Ce, Sr and La were found to be very active and selective materials under 0.67% CH4/0.2% NO/5% O2 "lean-deNOx" conditions in the 200-300°C low-temperature ...

Comparative study of La-Sr-Fe-O perovskite-type oxides prepared by ceramic and surfactant methods over the CH4 and H2 lean-deNOx
Stathopoulos, Vassilis N.; Belessi, Vassiliki C.; Bakas, Thomas V.; Neophytides, Stylianos G.; Costa, Costas N.; Pomonis, Phillippos J.; Efstathiou, Angelos M. (2009)Mixed oxides of the general formula La0.8Sr0.2FeO3-x were prepared by ceramic and surfactant methods and tested towards the NO/H2/O2 and NO/CH4/O2 lean-deNOx reactions in the 200-450 °C range. The materials were characterized ...

An investigation of the NO/H2/O2 (Lean De-NOx) reaction on a highly active and selective Pt/La0.7Sr0.2Ce0.1FeO3 catalyst at low temperatures
Costa, Costas N.; Savva, Petros G.; Andronikou, Ch; Lambrou, Panayiota S.; Polychronopoulou, Kyriaki; Belessi, Vassiliki C.; Stathopoulos, Vassilis N.; Pomonis, Phillippos J.; Efstathiou, Angelos M. (2002)A 0.1 wt% Pt supported on La0.7Sr0.2Ce0.1FeO3 solid (mixed oxide containing LaFeO3, SrFeO3-x, CeO2, and Fe2O3 phases) has been studied for the NO/H2/O2 reaction in the 100-400°C range. For a critical comparison, 0.1 wt% ...

An investigation of the NO/H2/O2 (Lean-deNOx) reaction on a highly active and selective Pt/La0.5Ce0.5MnO3 catalyst
Costa, Costas N.; Efstathiou, Angelos M.; Stathopoulos, Vassilis N.; Belessi, Vassiliki C. (2001)The NO/H2/O2 reaction has been studied under lean-burn conditions in the 100-400°C range over 0.1 wt% Pt supported on La0.5Ce0.5MnO3 (mixed oxide containing LaMnO3, CeO2, and MnO2 phases). For a critical comparison, 0.1 ...
