用TiCl_4,AlCl_3混胶法制备了TiO_2/γ-Al_2O_3负载型载体。发现该载体具有优良的孔结构。XRD,XPS的研究发现,随着TiO_2负载量的增加,TiO_2/γ-Al_2O_3负载型载体存在着四种分散状态和表面结构。ISS实验还发现γ-Al_2O_3表面的能量中心是不均匀的,有强位作用中心和弱位作用中心,TiO_2在γ-Al_2O_3表面上分散总是优先结合在强位作用中心上。TEM的研究发现TiO_2/γ-Al_2O_3载体具有两种微观结构。 TiO 2 / γ-Al 2 O 3 supported carriers were prepared by the mixed process of TiCl 4 and AlCl 3. The carrier was found to have an excellent pore structure. The results of XRD and XPS show that with the increase of TiO 2 loading, there are four kinds of dispersion states and surface structures of TiO 2 / γ-Al 2 O 3 supported carriers. ISS experiments also found that the energy centers of γ-Al 2 O 3 surface are inhomogeneous, and there are strong center of action and weak center of action. The dispersion of TiO 2 on γ-Al 2 O 3 surface always preferentially binds to strong center of action. TEM study found that the TiO 2 / γ-Al 2 O 3 carrier has two microstructures.
