Photoemission study of cerium silicate model systems
Tomáš Skála,Vladimír Matolín +1 more
TL;DR: In this paper, photoelectron spectroscopy was used to study the interaction of silicon with cerium oxide using two model systems CeO x /Si(1.67 Si 3 O 13 ) and Si/CeO 2 (1.1 ǫ)/Cu(1ǫ) which can be used for fundamental studies in the field of microelectronics and heterogeneous catalysis.

Ir/ZSM-5/cordierite monolith for catalytic NOx reduction from automobile exhaust
TL;DR: In this paper, a promising catalyst for the reduction of nitrogen oxides from automobile exhaust under both stoichiometric combustion and lean conditions was studied. But the performance of the proposed catalyst was limited by the fact that it exhibited good catalytic activity approaching commercial three-way catalysts.

Rh-Loaded CeO2-ZrO2 Solid-Solutions as Highly Efficient Oxygen Exchangers: Dependence of the Reduction Behavior and the Oxygen Storage Capacity on the Structural-Properties
Paolo Fornasiero,R. Dimonte,Gangavarapu Ranga Rao,Jan Kašpar,S. Meriani,Alessandro Trovarelli,Mauro Graziani +6 more
TL;DR: In this paper, it is shown that incorporation of ZrO2 into a solid solution with CeO2 strongly promotes bulk reduction of the Rh-loaded solid solutions in comparison to a Rh/CeO2 sample.

Twenty-five years after introduction of automotive catalysts: what next?
TL;DR: The union of catalysts and the automobile has been one of the greatest successes of heterogeneous catalysis over the last 25 years as mentioned in this paper, and there will be continued research and development activity focused also on downstream applications (i.e. exhaust emission aftertreatment), especially for fuelefficient, lean-burn vehicles, both diesel and spark-ignited.
