In the present work, the catalytic decomposition or oxidation of ethanol over CuO/CeO₂/γ-alumina catalysts is presented. Ethanol was oxidized in a tubular flow reactor under both oxygen excess and deficit conditions. Various amounts of ceria (0–14 % w/w) were added by wet impregnation to catalysts containing 1 % and 10 % w/w CuO on γ-Al₂O₃. Ceria addition affected catalyst performance mostly at low CuO loading and the formation of the main reaction products, namely acetaldehyde and carbon dioxide, depended strongly on oxygen concentration. The formation of the rest reaction products (i.e., ethylene and diethylether) depended on both oxygen concentration and amount of ceria on the catalyst used.
