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:

Nanomaterials of high surface energy with exceptional properties in catalysis and energy storage
TL;DR: This critical review presents a review of the progress made for producing shape-controlled synthesis of nanomaterials of high surface energy using electrochemical and wet chemistry techniques and discusses important nanommaterials such as nanocrystal catalysts based on Pt, Pd, Au and Fe, metal oxides TiO(2) and SnO( 2), as well as lithium Mn-richMetal oxides.

Atomically dispersed supported metal catalysts.
TL;DR: The development of effective synthesis methods and the identification of suitable stabilizers and promoters are expected to lead to the increasing application of atomically dispersed noble metal catalysts for practical processes characterized by efficient resource utilization and cost savings.

TL;DR: In this article, a semi-quantitative electron microprobe study showed that the association of lead compounds to the surface of Pt, Pd and Rh was at least 2 or 3 orders of magnitude higher compared to the amount found on the supports.

Optimization of ruthenium-containing, stabilized, nitric oxide reduction catalysts
TL;DR: In this article, the authors studied dilution of ruthenium by Ni3+ and Mn4+ ions in presynthesized specimens and the effect of stabilizer content in sequentially impregnated specimens.

Aging-induced metal redistribution in bimetallic catalysts
TL;DR: In this article, the compositional structure of some of the alloy particles was determined, and two different effects of the redistribution of metals on oxygen-storage capacity were identified, one due to Pd enrichment of the surface of Pd-Rh alloy particles and the other due to loss of contact between metal and ceria-zirconia.
