摘要：

In this article, M-Fe2O3-CuO (M: Mn, Ag and Co) mixed oxides nanocatalysts were synthesized by a novel ultrasound -assisted hydrothermal method and the effect of irradiation power and time on the physicochemical and catalytic properties in oxidation of carbon monoxide at low temperature was investigated. The synthesized samples were studied using XRD, BET, TPR and SEM techniques. The results indicated that the incorporation of Mn into Cu-Fe catalyst had a significant influence on the catalytic properties and the catalyst promoted with 10 wt% Mn exhibited the full conversion of CO at 100 degrees C. This catalyst possessed a high BET area (145.1 m(2) g(-1)) and a mesoporous texture with a relatively narrow pore size distribution with a mean crystal size of 13 nm.
