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:

Catalytic NO–CO–C3H6–O2 reactions over hydrothermally stable Rh-supported ZrP2O7 catalyst
TL;DR: In this article, a facile hydrothermal synthetic route for ZrP2O7 from ZrO(OH)2 and H3PO4 has been developed to use this as an active support for Rh catalyst.

STM and ARPES Study of Ordered Ce Film and Its Initial Oxidation
TL;DR: In this paper, ordered Ce metal films were grown on a W (110) substrate by molecular beam epitaxy (MBE) method in ultra-high vacuum (UHV) and subsequent annealing.
Journal ArticleDOI
Comparative analysis of NOx reduction on Pt, Pd, and Rh catalysts by DFT calculation and microkinetic modeling
TL;DR: In this article , DFT calculation was performed to identify the reaction mechanism of NO reduction on Pt, Pd and Rh catalysts under TWC conditions, and it was confirmed that Pt sufficiently reduces NO using H 2 under stoichiometric and fuel-lean conditions, while it hardly reduces NO in presence of O 2 .
ANNIVERSARY ARTICLE Air Pollution: A Half Century of Progress
TL;DR: In the 50 years since the air pollution episodes of Donora, PA and London, U.K., a great deal of progress has been made in understanding the nature and sources of air pollution and the atmospheric transport and transformation of pollutants.

Catalytic reduction of NO by CO over supported Pd catalysts: effect of the thermal treatments
TL;DR: In this paper, the reduction of NO by CO at 200°C, employing the pulse technique, was studied using the catalytic activity of Pd(7%)/Al2O3, Pd[7]-/La2O-3-Al 2O3 catalysts.

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.

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.
