      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 ...
