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:

Synthesis of CeO2–MnOx mixed oxides and catalytic performance under oxygen-rich condition
TL;DR: In this article, the effect of manganese on the structural and redox properties of ceria-based mixed oxides was investigated by means of powder X-ray diffraction, Xray photoelectron spectroscopy, Brunauer-Emmett-Teller analyses, temperature-programmed reduction and catalytic activity evaluation in the presence of excess O 2.
Journal ArticleDOI
The Pr promotion effect on oxygen storage capacity of Ce–Pr oxides studied using a TAP reactor
TL;DR: In this article, the authors measured the oxygen storage capacity including OSC, OSCC and dynamic OSC for Ce-Pr oxides using a temporal analysis of products (TAP) reactor system, and the exact features of reduction and re-oxidation were obtained by accurately measuring the uptake of CO and O and the production of CO 2.
Journal ArticleDOI
Low-temperature SCR of NO with NH3 over activated semi-coke composite-supported rare earth oxides
TL;DR: In this paper, the selective catalytic reduction (SCR) of NO with NH3 at low temperature (150-300°C) was investigated through various characterizations, including XRD, Raman, XPS and FT-IR, which indicated that the oxygen defect plays an important role in SCR process and the doped rare earth elements effectively serve as promoters to increase the concentration of oxygen vacancies.
Journal ArticleDOI
Remarkable NO oxidation on single supported platinum atoms.
TL;DR: The overall picture of NO oxidation on supported Pt is that NO oxidation activity decreases with decreasing Pt particle size but accelerates when Pt is present only as single atoms.
Journal ArticleDOI

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.
