Effect of CexZryLazOδ mixed oxides on the structural and catalytic behavior of monometallic catalytic converters under simulated exhaust conditionsEffect of CexZryLazOδ mixed oxides on the structural and catalytic behavior of monometallic catalytic converters under simulated exhaust conditions Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-162009enThe effect of CeO2, La2O3 and ZrO2 structural stabilizers/promoters, in the form of CexZryLazOδ mixed oxides, on the catalytic performance and thermal stability of monometallic (Pt), monolithic-type, Al2O3-washcoated three-way catalytic converters (TWCs) was investigated under simulated exhaust conditions. The evolution of textural, structural and surface behavior of CexZryLazOδ modified TWCs were identified by means of X-ray diffraction (XRD), transmission electron microscopy (TEM) and diffuse reflectance infrared spectroscopy (DRIFTS) and appropriately correlated with the catalytic behavior and thermal stability of TWCs.http://creativecommons.org/licenses/by/4.0/Topics in Catalysis52131873-1879 Tsetsekou A.
