Abstract
In this study, CuO/CeO 2 Nano-catalyst was successfully prepared by impregnation-ultrasound assisted methods and used for selective oxidation. This catalyst has been characterized by means of XRD, BET, FTIR and SEM. The results show that CuO/CeO2 is nanosized (rSEM < 100 nm) and BET surface area of tested materials was in the range of 45–76 m 2/g. CuO is the active phase for selective CO oxidation, even operating at a gas hourly space velocity as high as 30000 h -1 . The catalysts CuO/CeO 2 exhibit the CO conversion 100% in the wide temperature range of 100–120 °C, and with the CO oxidation selectivity greater than 86% at 100 ◦C.
