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:

Diesel soot combustion catalysts: review of active phases
TL;DR: The most relevant information about the different active phases that have been studied for the catalytic combustion of soot is reviewed and discussed in this paper, where metal oxide-based catalysts appear to be promising candidates for soot combustion in practical applications, including ceria-based formulations and mixed oxides with perovskite and spinel structures.

Aging, re-dispersion, and catalytic oxidation characteristics of model Pd/Al2O3 automotive three-way catalysts
TL;DR: In this article, the aging characteristics of model automotive Pd/Al 2 O 3 catalyst materials were examined under simulated aging and light-off conditions as a function of aging temperature (up to 1000°C) in both reducing and oxidizing gas mixtures.

SCR of NO by propene over nanoscale LaMn1−xCuxO3 perovskites
TL;DR: In this paper, the performance of the LaMnO 3 perovskites with high specific surface areas was characterized by N 2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM), H 2 -temperature programmed reduction (TPR), O 2 -, NO+O 2 - and C 3 H 6 -temper programmed desorption (TPD) under C 3H 6 /He flow.

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.
