| 英文摘要 | the effects of ceo2 contents and silica carrier porosity with their pore diameters ranging from 5.2 nm to 12.5 nm of cuo-ceo2/sio2 catalysts in co oxidation were investigated. the catalysts were characterized by n-2 adsorption/desorption at low temperature, x-ray diffraction (xrd), temperature-programmed reduction by h-2 (h-2-tpr), oxygen temperature programmed desorption (o-2-tpd) and x-ray photoelectron spectroscopy (xps). the results suggested that, the ceria content and the porosity of sio2 carrier possessed great impacts on the structures and catalytic performances of cuo-ceo2/sio2 catalysts. when appropriate content of ceo2 (ce content <= 8 wt%) was added, the catalytic activity was greatly enhanced. in the catalyst supported on silica carrier with larger pore diameter, higher dispersion of cuo was observed, better agglomeration-resistant capacity was displayed and more lattice oxygen could be found, thus the cuo-ceo2 supported on si-1 showed higher catalytic activity for low-temperature co oxidation. |
