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:

Three way catalytic activity of thermally degenerated Pt/Al2O3 and Pt/CeO2–ZrO2 modified Al2O3 model catalysts
TL;DR: The effect of ceria and ceria-zirconia modification to alumina on the three-way catalytic (TWC) performance of alumina supported Pt catalyst was investigated in this paper.

Core-shell type ceria zirconia support for platinum and rhodium three way catalysts
TL;DR: Ceria zirconia support with core-shell structure was investigated as a novel item for platinum and rhodium three way catalysts (TWC) in this paper, which can provide a number of active sites, resulting in the total oxygen storage capacity (OSC) value of 2.7ml/g when Ce/Zr = 1/9.

Seasonal and Spatial Coarse Particle Elemental Concentrations in the Los Angeles Area
TL;DR: In this article, the concentrations of trace metals and elements in the coarse fraction of atmospheric particulate matter (CPM, particles smaller than 10 and larger than 2.5 μm in diameter, PM10-2.5) and their spatial and temporal trends were investigated in the greater Los Angeles area.

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.
