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:

Reaction kinetic parameters for a distributed model of transport and reaction in Pd/Rh/CeZrO three-way catalytic converters
TL;DR: In this article, a two-dimensional distributed model for the transport and reaction of combustion gases in channels of three-way catalytic converters, considering a detailed reaction kinetics with 16 chemical reactions in palladium and rhodium catalysts, and taking into account diffusive effects within the coating, was presented.

Chromia on Anatase: A Catalyst for Selective Hydrocarbon Combustion in the Presence of CO
TL;DR: The catalytic activity and selectivity for propane combustion in the presence of CO have been studied with anatase, rutile, eskolaite, chromia-impregnated anatase and its physical mixtures as mentioned in this paper.

When ruthenia met titania: achieving extraordinary catalytic activity at low temperature by nanostructuring of oxides
Jesús Graciani,Fan Yang,Jaime Evans,Alba B. Vidal,Alba B. Vidal,Dario Stacchiola,José A. Rodriguez,Javier Fdez. Sanz +7 more
TL;DR: Nanostructured ruthenia shows strongly modified properties compared to the pure oxide, consolidating the fact that the nanostructuring of oxides is a main way to attain higher catalytic activity at lower temperatures.
Dissertation
Characterization of automotive catalyst ageing
TL;DR: In this article, the effect of different ageing methods on catalytic systems for cars was investigated, and it was shown that the poison seemed to have a greater effect on the oxygen storage capacity, while the thermal ageing affected the light-off characteristics more.

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.
