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.

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.

Support nanostructure boosts oxygen transfer to catalytically active platinum nanoparticles

TL;DR: This study identifies two types of oxidative metal-oxide interaction on well-defined models of technologically important Pt-ceria catalysts and details the formation mechanism of the catalytically indispensable Pt-O species on ceria to elucidate the extraordinary structure-activity dependence of ceria-based catalysts in general.

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.

Affinity of lead for noble metals on different supports

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.
Journal ArticleDOI

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.
