Ceria-zirconia thin-film crystals for electron microscopy studies of metal-support interactions in model automotive-exhaust catalysts

Lead Institution

University of Michigan

Principal Investigator

George Graham

Project type

Exploratory Research

Cerium-zirconium mixed oxides are used to support precious metals and provide oxygen storage in current automotive-exhaust catalysts. Deactivation of these catalysts with time-in-use is a matter of…

Principal Investigator

Xiaoqing Pan

Project type

Large-Scale EMSL Research

Ceria and ceria-based oxides have been widely investigated as electronic promoters of activity, selectivity, and thermal stability in a variety of catalysts. Pd on ceria-based supports is an…
