Automotive exhaust catalysis
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:

Dissertation
Diesel oxidation NOx adsorption catalysts
TL;DR: In this article, the authors investigated the effect of the support material on the performance of supported platinum catalysts in diesel engines and found that the catalytic capacity of the supported catalysts is greatly affected by the structure and acidity of the zeolite support material, in general, their performance is enhanced by adding SiO2 to the TiO2 support.

Separation of Pt and Pd from chloride solutions by liquid–liquid extraction using Alamine 308 and analysis of their mechanism: A possible recovery from spent auto catalysts
Basudev Swain,Jae-chun Lee +1 more
TL;DR: In this paper , the effect of different process parameters such as the concentrations of HCl, NaCl, platinum, and palladium in the aqueous solution, and the concentration of Alamine 308 in the organic phase, on the separation behavior, was evaluated.

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.
Book
Catalytic Air Pollution Control: Commercial Technology
TL;DR: In this paper, the authors present an overview of the history of catalytic components in diesel engines and their application in a variety of applications, such as catalytic converter, catalytic converters, and catalytic monoliths.

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.
