摘要

Abstract

The Fe-modified sepiolite-supported Mn-Cu mixed oxide (CuxMny/Fe-Sep) catalysts were prepared using the co-precipitation method. These materials were characterized by means of the XRD

adsorption-desorption

XPS

-TPR

and O

-TPD techniques

and their catalytic activities for CO and ethyl acetate oxidation were evaluated. The results show that catalytic activities of the CuxMny/Fe-Sep samples were higher than those of the Cu1/Fe-Sep and Mn2/Fe-Sep samples

and the Mn/Cu molar ratio had a distinct influence on catalytic activity of the sample. Among the CuxMny/Fe-Sep and Cu1Mn2/Sep samples

Cu1Mn2/Fe-Sep performed the best for CO and ethyl acetate oxidation

showing the highest reaction rate and the lowest

and 210℃ for ethyl acetate oxidation

respectively. Moreover

the Cu1Mn2/Fe-Sep sample possessed the best lowtemperature reducibility and the lowest temperature of oxygen desorption as well as the highest surface Mn

/Mn

and Cu

/CuO atomic ratios. It is concluded that factors

such as the strong interaction between the Cu or Mn and the Fe-Sep support

good low-temperature reducibility

and good mobility of chemisorbed oxygen species

might account for the excellent catalytic activity of Cu1Mn2/Fe-Sep.
