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:

Ageing resistance of rhodium supported on CeO2–ZrO2 and ZrO2: Rhodium nanoparticle structure and Rh–support interaction under diverse ageing atmosphere
TL;DR: In this paper, the nanostructure, oxidation state, and redox properties of rhodium were characterized by X-ray diffraction, CO chemisorption, H2 temperature-programmed reduction, transmission electron microscopy, and Xray photoelectron spectroscopy.

Configurational Thermodynamics of Alloyed Nanoparticles with Adsorbates
TL;DR: The cluster expansion method is extended to predict the configurational thermodynamics of alloyed NPs with adsorbates based on density functional theory data and fully detail the core-shell behavior across the entire range of NP composition and O-coverage with quantitative agreement to in situ experimental data.
Journal ArticleDOI
CeO2 grafted with different heteropoly acids for selective catalytic reduction of NOx with NH3.
TL;DR: H2-TPR and XPS and DRIFTS results indicated that reducibility of HPMo/CeO2 was stronger than those of HSiW/CEO2 and HPW/ cEo2, resulting in the high-temperature performance loss.

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.
