      N2O decomposition over ceria-promoted Ir/Al2O3 catalysts: The role of ceria 

      Pachatouridou, E.; Papista, E.; Delimitis, Andréas; Vasiliades, Michalis A.; Efstathiou, Angelos M.; Amiridis, Michael D.; Alexeev, O. S.; Bloom, D.; Marnellos, G. E.; Konsolakis, M.; Iliopoulou, E. (2016)
      The impact of CeO2 in the Al2O3-20wt% CeO2 support prepared by the co-precipitation method on the Ir particle size, morphology and oxidation state, and in turn on the deN2O catalytic activity (1000ppmN2O) of supported Ir ...

      Oxy-chlorination as an effective treatment of aged Pd/CeO 2-Al 2O 3 catalysts for Pd redispersion 

      Lambrou, Panayiota S.; Polychronopoulou, Kyriaki; Petallidou, Klito C.; Efstathiou, Angelos M. (2012)
      The present work reports on the effects of oxy-chlorine gas treatment (use of Cl 2/O 2/He gas mixture) applied on a 5wt% Pd/20wt% CeO 2-Al 2O 3 catalyst towards Pd redispersion. X-ray diffraction (XRD), X-ray photoelectron ...

      Water-gas shift reaction on Pt/Ce1- xTixO 2-δ: The effect of Ce/Ti ratio 

      Petallidou, Klito C.; Polychronopoulou, Kyriaki; Boghosian, Soghomon; Garcia-Rodriguez, S.; Efstathiou, Angelos M. (2013)
      Pt nanoparticles (1.2-2.0 nm size) supported on Ce1-xTi xO2-δ (x = 0, 0.2, 0.5, 0.8, and 1.0) carriers synthesized by the citrate sol-gel method were tested toward the water-gas shift (WGS) reaction in the 200-350 C range. ...
