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:

Catalytic performance and mechanistic evaluation of sulfated CeO2 cubes for selective catalytic reduction of NOx with ammonia.
TL;DR: Sulfated CeO2 cubes were further characterized by atom-resolved high angle annular dark-field (HAADF) imaging, Fourier transform infrared spectroscopy (FTIR) by pyridine adsorption, and temperature-programmed reduction by H2 (H2-TPR).

Mapping the shape and phase of palladium nanocatalysts
TL;DR: In this paper, the authors present results of theoretical modeling, based on first principle computer simulations, exploring the equilibrium and non-equilibrium morphologies of palladium nanoparticles over the entire nanoscale.
Journal ArticleDOI
Development of Ceria-Supported Ruthenium Catalysts Effective for Various Synthetic Reactions
TL;DR: In this article, a simple, recyclable heterogeneous Ru/CeO2 catalyst showed excellent activity for sequential transfer-allylation/isomerization of homoallyl alcohols with aldehydes to saturated ketones via the C-C bond activation.
Journal ArticleDOI
Nano-Array Integrated Structured Catalysts: A New Paradigm upon Conventional Wash-Coated Monolithic Catalysts?
TL;DR: In this paper, a new type of nano-array-integrated structured catalysts is proposed, which is composed of honeycomb-structured monoliths whose channel surfaces are grown in situ with a nanoarray forest made of traditional binary transition metal oxide support such as Al2O3, CeO2, Co3O4, MnO2 and ZnO2.

Muriel Lepage,Tom Visser,Fouad Soulimani,Andrew M. Beale,Ana Iglesias-Juez,Ad M. J. van der Eerden,Bert M. Weckhuysen +6 more
TL;DR: In this paper, the effect of promotor elements in the oxidation of CO in excess oxygen was investigated using time-resolved infrared spectroscopy measurements, and the most promoted CO oxidation catalyst is a Pt/K-Y sample with a T50% of 390 K and a L:B intensity ratio of 2.7.

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.

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.
