Abstract
- A deactivated (aged under redox-cycled model TWC feed-stream) Pd/Ce<SUB>0.68</SUB>Zr<SUB>0.32</SUB>O<SUB>2</SUB> catalyst is remarkably reactivated when subjected to a high temperature oxidising treatment whereas this effect is only marginal for Pd/Al<SUB>2</SUB>O<SUB>3</SUB>, which indicates the key role of such treatment in restoring the PdCe<SUB>0.68</SUB>Zr<SUB>0.32</SUB>O<SUB>2</SUB> interactions leading to highly active catalysts.
