| Abstract: | 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. |
