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:

Design of functional composite and all-inorganic nanostructured materials via infiltration of polymer templates with inorganic precursors
Diana Berman,Elena V. Shevchenko +1 more
TL;DR: In this paper, the authors outline the specifics and dynamics of the polymer infiltration process and characterize the structure and properties of the synthesized materials, and highlight recent progress in implementing polymer infiltration-based nanoporous ceramics for many applications, including sensors, antireflective coatings, oil absorbing foams, nanolithographic patterns, and catalytic materials.

The influence of temperature on the deactivation of commercial Pd/Rh automotive catalysts
Daniela Meyer Fernandes,Cynthia Fraga Scofield,Arnaldo Alcover Neto,Mauri José Baldini Cardoso,Fatima Maria Zanon Zotin +4 more
TL;DR: In this paper, the effect of temperature on the performance of Pd/Rh-based automotive catalysts has been investigated for CO and propane oxidation with a stoichiometric gas mixture similar to engine exhaust gas.
Journal ArticleDOI
An experimental and kinetic modeling study of aging impact on surface and subsurface oxygen storage in three-way catalysts
TL;DR: In this paper, the aging impact on oxygen storage capacity (OSC) of three-way catalysts was investigated through experiments and modeling, and it was found that not only the quantities of oxygen storage sites decreased but also the qualities of storage sites (rate constants) declined after aging.
Journal ArticleDOI
Oxygen Coverage Dependence of NO Oxidation on Pt(111)
TL;DR: In this article, the interaction of NO with adsorbed atomic oxygen on Pt(111) was studied with temperature programmed desorption (TPD), infrared reflection absorption spectroscopy (IRAS), and low-energy electron di...

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.
