Au/MgF2 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 MgF2 surface. Its activity decreases (in contrast to Au/MgO) after the hydrogen pre-treatment. Higher activities of Au/MgF2 as compared to Au/MgO prepared in the same conditions, can be due to smaller Au particle size on the MgF2 support as shown by TEM, and to the presence of anionic Au delta– species.
