abstract in English:	A series of γ-Al2O3, TiO2 (anatase) and mt-ZrO2 were impregnated with 1.0 wt.% of Cu or Fe and/or with 0.05 wt.% of Pt, Pd or Rh. The obtained samples were tested as catalysts of the selective catalytic oxidation of ammonia. An interesting class of zirconia and titania supported catalysts is based on copper. Modification of these catalysts with noble metals significantly decreased temperature of the ammonia oxidation. Platinum doped catalysts exhibited the highest activity, while rhodium based materials were the most selective catalysts in the studied temperature range. Catalytic performances of tested materials were consistent with their redox properties.
