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:

Exceptional high-temperature stability through distillation-like self-stabilization in bimetallic nanoparticles
An-Min Cao,Götz Veser,Götz Veser +2 more
TL;DR: It is found that PtRh nanoparticles with sufficiently high Rh content survive extended calcination at temperatures up to approximately 850 degrees C without significant sintering and should be broadly applicable to the development of multi-metallic nanomaterials for a broad range of high-temperature applications.
Journal ArticleDOI
Stable isolated metal atoms as active sites for photocatalytic hydrogen evolution
Jun Xing,Jianfu Chen,Yu Hang Li,Wen Tao Yuan,Ying Zhou,Lirong Zheng,Haifeng Wang,Peijun Hu,Peijun Hu,Yun Wang,Huijun Zhao,Yong Wang,Hua Gui Yang,Hua Gui Yang +13 more
TL;DR: For the first time, isolated metal atoms (Pt, Pd, Rh, or Ru) stably by anchoring on TiO2 are synthesized by a facile one-step method and show excellent stability for H2 evolution and can lead to a 6-13-fold increase in photocatalytic activity over the metal clusters loaded on TiOs by the traditional method.
Journal ArticleDOI
Selective catalytic reduction of NO over supported silver catalysts—practical and mechanistic aspects
Ken-ichi Shimizu,Atsushi Satsuma +1 more
TL;DR: The current research of supported Ag catalysts is reviewed from the viewpoints of practical use and the reaction mechanism, i.e., the reaction scheme, the role of surface adsorbed species, and the structure of active Ag species.
Journal ArticleDOI
Electrochemical preparation of Pd nanorods with high-index facets
TL;DR: Fivefold twinned Pd nanorods bounded by high-index facets of {hk0} or {hkk} were prepared by an electrochemical method and tested as electrocatalysts of high activity for ethanol oxidation.
Journal ArticleDOI
Shape dependence and sulfate promotion of CeO2 for selective catalytic reduction of NOx with NH3
TL;DR: In this article, sulfation treatment was used to improve the catalytic performance of NH3-SCR on both CeO2 cubes and nanospheres, and the results showed that sulfated cubes outperformed nonsulfated cubes in the entire test temperature window (200-500°C).

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.
Journal ArticleDOI
Nitric oxide catalysis in automotive exhaust systems
TL;DR: In this paper, a review of the literature on NO catalysis is presented, focusing on the threeway catalyst system which simultaneously promotes the reduction of nitrogen oxides and the oxidation of carbon monoxide and hydrocarbons.

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.
