Abstract: Ceria with different morphology was prepared by a hydrothermal method. The coll oidal deposition method selected to prepare the catalysts allowed the isolation of the support effect on the catalytic activity and excluded the influence of go ld particle formation by their deposition on the support. The activity of the Au /CeO2 catalysts for CO oxidation was investigated.

Key words: gold, carbon monoxide oxidation, ceria, crystal plane
