POWDER CATALYST SUPPORT AND EXHAUST TREATING CATALYST Russian patent published in 2009 - IPC B01J21/06 B01J23/10 B01J32/00 B01J23/42 B01J23/63 B01D53/94

Abstract RU 2354449 C1

FIELD: chemistry.

SUBSTANCE: present invention refers to powder catalyst support and related exhaust treating catalyst. There is disclosed powder catalyst support containing cerium dioxide and zirconium dioxide where molar concentration (mol. %) of cerium dioxide on powder catalyst surface under measurements of X-ray photoelectron spectroscopy to molar concentration (mol. %) of cerium dioxide in source material is within 1.0 to 1.5. Besides, in the present invention there is disclosed exhaust treating catalyst containing said powder support with coated platinum.

EFFECT: higher thermal stability and catalytic activity of the catalyst.
