| 英文摘要 | a series of al-doped ceo(2) catalysts (n-alceo(2), where n represents the molar ratio of cc to al in the samples) were prepared by a citric acid complexation-combustion method and used for soot combustion. there is a strong interaction between ceo(2) and al(2)o(3) in the mixed oxide, and some aluminum can be incorporated into the ceo(2) lattice forming a solid solution. the existence of gamma-al(2)o(3) in the mixed oxide obviously improved the thermal stability of ceo(2) as a "diffusion barrier", which induced a higher catalytic activity of the mixed oxides compared with the pure ceo(2). for the al-containing samples, the mobility of surface lattice oxygen seems to play an important role in soot combustion. the 30-alceo(2) sample exhibited the highest soot combustion activity with the temperature corresponding to the co(2) + co peak of 356 degrees c. |
