Abstract:The new nanosolid superacid SO42-/CoFe2O4 is prepared by using nanometer chemical technology.The structure of catalysis has been studied by XRD, TEM, IR, XPS and BET methods.The results show that SO42-/CoFe2O4 is superfine solid(< 50nm) belong to nanocrystal and has high specific surface area (157m2·g-1).SO42- is combined with metal ions of catalysis in a bidentate state.The catalytic activity and strength of acid (H0 < -14.5) is measured by the model reaction of the synthesis of ethyl acetate.
Keywords:SO42-/CoFe2O4  nanosolid superacid  structural characterization  catalytic activity  ethyl acetate
