POWDER CATALYST SUPPORT AND EXHAUST TREATING CATALYST

摘要

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. ^ 10 cl, 3 dwg, 2 tbl
