摘　　要：SO42-/TiO2/Fe3O4 supporting Ni catalyst was synthesized via the sol-gel technology.It is a bifunctional catalyst that could be employed in both metal catalytic and acid catalytic processes and separated by magnetic field.XRD,TEM,and FT-IR were performed on the catalyst with reference to its structure,particle size,acidity,and Ni loading.SO4^2-/TiO2/Fe3O4 supporting Ni catalyst was synthesized via the sol-gel technology. It is a bifunctional catalyst that could be employed in both metal catalytic and acid catalytic processes and separated by magnetic field. XRD, TEM, and FT-IR were performed on the catalyst with reference to its structure, particle size, acidity, and Ni loading.
