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:

Activation of Oxygen in Ce2Zr2O7+x across Pyrochlore to Fluorite Structural Transformation: First-Principles Analysis
TL;DR: In this paper, the structural evolution of the pyrochlore-Ce2Zr2O7+z from the fluorite structure of Ce0.5Zr 0.5O2 (Ce 2Zr 2O8+z) to fluorite-ce2zr 2 O8 (c = 1) using first-principles density functional theoretical calculations and bond-valence theory was analyzed.

Thermal Stable Pd/Ce0.2Y0.8O2-δ Catalysts for CO and CH4 Oxidation
TL;DR: In this paper, a series of Pd/Ce0.2Y0.8O2-δ catalysts were tested for CO and CH4 oxidation and it was found that the catalysts are thermal stable, and the catalytic activity enhances with increasing calcination temperature.
Journal ArticleDOI
Influence of Al2O3/CeZrAl composition on the catalytic behavior of Pd/Rh catalyst
TL;DR: In this article, the surface area, oxygen storage capacity (OSC) and H 2 adsorption capacity (TPR) of fresh and aged Pd/Rh samples were examined by means of BET and TPR.
Journal ArticleDOI
Molecular simulations of physical and chemical adsorption under gas and liquid environments using force field- and quantum mechanics-based methods
Baxter M. Ward,Rachel B. Getman +1 more
TL;DR: In this paper, the simulations of adsorption on metal-organic frameworks (MOFs) and platinum (Pt) catalysts are reviewed, focusing on the modelling methods required to understand these two very different systems.

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.
