<正> Ce0.6Zr0.4O2 solid solution was prepared by co-precipitation technique using hydrazine hydrate as precipitator. Various physico-chemical techniques such as XRD, FT-Raman, SEM, TEM, etc. were used to characterize the resultant powder. Meanwhile, its catalytic activity was evaluated in the synthesis of n-butyl acetate by the reaction of acetic acid and n-butyl alcohol. The results show that ceria-zirconia solid solution forms single cubic structure and its particle diameter is less than 100 nm. As a sort of solid acid, it possesses high catalytic activity and can be easily separated from reaction liquid. After it is used for ten times, its activity basically kees unchanging.
