• Au/MgF(2)
• Au/MgO catalysts
• CO oxidation

Au/MgF(2) catalyst is more active in CO oxidation than Au/MgO prepared in the same conditions, in spite of lower efficiency of Au deposition on the MgF(2) surface. Its activity decreases (in contrast to Au/MgO) after the hydrogen pre-treatment. Higher activities of Au/MgF(2) as compared to Au/MgO prepared in the same conditions, can be due to smaller Au particle size on the MgF(2) support as shown by TEM, and to the presence of anionic Au(delta-) species.
