چکیده
|
In this study, cuo/ceo2 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 m2/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/ceo2 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.
