      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 ...
