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:

Copper–Cobalt–Cerium Ternary Oxide as an Additive to a Conventional Platinum‐Group‐Metal Catalyst for Automotive Exhaust Catalysis
TL;DR: In this article, a ternary mixed-oxide catalyst that showed low-temperature CO oxidation activity under lean exhaust conditions without inhibition by hydrocarbons such as propene was reported.

Selective Oxidation of Cyclohexane Using Graphene Oxide-Supported Ceria Nanocomposites with Exposed Active {1 0 0} Facets
Selvamani Arumugam,Babu Cadiam Mohan,Srinivasan Vinju Vasudevan,Ramkumar Vanaraj,Balasubramanian Rukmanikrishnan,Thirukumaran Periyasamy,Shakila Parveen Asrafali +6 more
TL;DR: In this paper, the synthesis and characterization of ceria loaded graphene oxide (GO) and their catalytic activity on vapor phase selective oxidation of cyclohexane were investigated. And the authors concluded that a suitable amount of Ceria and it's flower-like morphology on GO is essential for high conversion (90%), due to occurrence of enormous {1 0 0} facet and Ce3+.

Heteroepitaxy of Cerium Oxide Thin Films on Cu(111)
TL;DR: The present contribution is devoted to development of a model catalyst system of CeO2 (ceria) on the Cu(111) substrate, proposing ways to experimentally characterize and control important parameters of the model catalyst—the coverage of the ceria layer, the influence of the Cu substrate, and the density of surface defects on ceria.

Analysing the Reaction Kinetics for Individual Catalytically Active Components: CO Oxidation on a Pd Powder Supported by Pt Foil
TL;DR: In this paper, a model of CO oxidation on a model catalyst consisting of Pd powder agglomerates supported by a polycrystalline Pt foil is presented. And the kinetic data for the micrometer-sized Pt(100) and Pt(110) domains and for the different pd powder ag-glomerates of similar dimensions were obtained by local analysis of PEEM video-sequences recorded in situ during the ongoing CO oxidation reaction.
Journal ArticleDOI
High energy surface x-ray diffraction applied to model catalyst surfaces at work
TL;DR: General considerations of HESXRD are reviewed including its working principle for different model catalyst samples and the experimental equipment required and an outlook on future perspectives and applications is given.

Catalysis by Ceria and Related Materials
TL;DR: The use of ceria-based catalysts in automotive catalysts was discussed in this paper, where the authors showed that the properties and thermal stability of Ceria-zirconia and related materials can be characterized using surface analysis techniques.

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.
