【Abstract】 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.更多还原
