“…Nevertheless, γ-Al 2 O 3 due to its high surface area (100-200 m 2 /g) and its good thermal stability is preferred to all other metal oxides (Kong et al, 2020;Panahi and Delahaye, 2017 (Hansen et al,2017). The drawbacks of noble-metal catalysts motivate the vehicle manufacturers to reduce their content or substitute them with cheaper Mn/Cu-based oxides catalysts (Damma et al, 2019).…”

Copper loaded η-alumina catalysts with different copper contents have been prepared by impregnation/evaporation method. The catalysts were characterized by XRD, FTIR, BET, UV-vis, H 2 -TPR and evaluated in the selective catalytic reduction of NO by NH 3 and in the selective catalytic oxidation of NH 3 . The characterization techniques showed that the impregnation/evaporation method permits to obtain highly dispersed copper oxide species on the η-alumina surface when low amount of copper is used (1wt. % and 2 wt.%). The wet impregnation method made it possible to reach a well dispersion of the copper species on the surface of the alumina for the low copper contents Cu( 1)-Al 2 O 3 and Cu(2)-Al 2 O 3 . The latter justi es the similar behavior of Cu(1)-Al 2 O 3 ) and Cu(2)-Al 2 O 3 in the selective catalytic oxidation of NH 3 where these catalysts exhibit a conversion of NH 3 to N 2 of the order of 100% at T > 500°C.
