TLDR
The general trend has been one of increasingly complex catalyst formulations in response to increasingly stringent emission standards as discussed by the authors, but with greater emphasis on optimizing catalyst formulations for lean-burn applications and reducing catalyst cost and complexity without sacrificing performance.About:

Stressing Pd atoms: Initial oxidation of the Pd(110) surface
Rasmus Westerström,C. J. Weststrate,Andrea Resta,Anders Mikkelsen,Joachim Schnadt,Jesper N Andersen,Edvin Lundgren,Michael Schmid,Nicola Seriani,Judith Harl,Florian Mittendorfer,Georg Kresse +11 more
TL;DR: In this paper, the authors investigated the oxygen induced structures of the Pd(1 1 0) surface in the pressure range of 10(-5)-10(-3) mbar of oxygen, at a sample temperature of around 300 degrees C.

NO Reduction Over Noble Metal Ionic Catalysts
Parthasarathi Bera,M. S. Hegde +1 more
TL;DR: In this paper, the authors explored an entirely new approach of dispersing noble metal ions in CeO2 and TiO2 for redox catalysis and found that these new generation noble metal ionic catalysts are much more catalytically active than conventional nano crystalline noble metal catalysts especially for NO reduction.
Journal ArticleDOI
Benzene: a secondary pollutant formed in the three-way catalyst.
TL;DR: To what extent and at what operating conditions catalyst-induced benzene and toluene formation can occur, a EURO-1 passenger car equipped with a new, two-layered, Pd-CeO 2-Al2O3/Rh-ZrO2-Al 2O3 three-way catalyst was operated.
Journal ArticleDOI
Improved propane photooxidation activities upon nano Cu2O/TiO2 heterojunction semiconductors at room temperature
TL;DR: In this paper, as-formed Cu2O/TiO2 heterojunctions with different weight percentage of Cu 2O were fabricated by a facile impregnating method for propane oxidation at room temperature.
Journal ArticleDOI
First-principles Analysis of NOx Adsorption on Anhydrous γ-Al2O3 Surfaces
TL;DR: In this paper, the interaction between NOx and gamma Al2O3 can be described as a surface mediated electron transfer process, which results in a favorable electrostatic interaction between two adsorbed NOx species.

Catalysis by Ceria and Related Materials
TL;DR: The use of ceria-based catalysts in automotive catalysts was discussed in this paper, where the authors showed that the properties and thermal stability of Ceria-zirconia and related materials can be characterized using surface analysis techniques.

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.
Journal ArticleDOI
Nitric oxide catalysis in automotive exhaust systems
TL;DR: In this paper, a review of the literature on NO catalysis is presented, focusing on the threeway catalyst system which simultaneously promotes the reduction of nitrogen oxides and the oxidation of carbon monoxide and hydrocarbons.

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.
