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:

Identifying the Surface Active Sites of Feox-Modified Pt/Nb2o5 Catalysts in Co and Propane Oxidation
Dissertation
Environmental-(S)TEM of dynamic Catalyst Nanostructures
TL;DR: In this paper, the authors used dynamic in-situ imaging in ETEM to observe the evolution of Pd nanoparticles under redox conditions and found that the amount of sintering was determined by both: gas environment and the support material.

Key role of NO + C 3 H 8 reaction for the elimination of NO in automobile exhaust by three-way catalyst
TL;DR: The reaction NO + C3H8 served as the key reaction in determining the purification efficiency of NO at the high-temperature stage and contributed to the higher NO elimination efficiency of Pd/CZA.

High three-way catalytic activity of rhodium particles on a Y-stabilized La-containing ZrO2 support: the effect of Y on the enhanced reducibility of rhodium and self-regeneration
Hisaya Kawabata,Hisaya Kawabata,Yuki Koda,Hirosuke Sumida,Masahiko Shigetsu,Akihide Takami,Kei Inumaru +6 more
TL;DR: In this article, a three-way catalyst, rhodium supported on Y-and La-added zirconia (Rh/Zr-Y-La-O), was found to have high steam reforming activity.
Journal ArticleDOI
Correlation of light-off activity for full size and cored catalyst samples
TL;DR: In this article, the authors identify and analyze the correlation that exists in the CO light-off performance of full size canned catalytic converters and cored samples taken from the front and rear sections of the same catalyst brick.

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.
