文摘

Pd/Ce0.5Sn0.5O2 catalysts for low temperature CO oxidation were prepared.

Solution combustion of all precursors leads to bulk Pd2 + ions distribution.

Impregnation of Ce0.5Sn0.5O2 by Pd leads to surface localized Pd2 + ions.

Impregnation method allows obtaining high activity of catalyst at low Pd content.
