研究了液相选择性沉积法制备的Ni-Zn/TiO 2纳米复合材料的表征。纳米粒子通过选择性沉积在TiO 2表面而得到了良好的分散和稳定.随着Zn添加量的增加，Ni的粒径减小，催化活性表面积增加。Zn在TiO 2表面的选择性沉积以及Zn的添加提高了Ni-Zn纳米粒子的催化活性，如Ni-Zn/TiO 2催化剂对1-辛烯加氢的催化活性约为100%。比未负载的Ni纳米颗粒高10倍。纳米复合材料中的Ni被指定为金属，尽管它们的表面在大气条件下被氧化，但Zn和B以氧化物形式沉积。
The characterization of Ni-Zn/TiO 2 nanocomposite synthesized by the liquid-phase selective-deposition method was studied. Nanoparticles were well dispersed and stabilized by the selective deposition onto TiO 2 surface. The particle size was decreased with increasing the amount of Zn added, thus the catalytically active Ni surface area was increased. The selective deposition onto TiO 2 surface and addition of Zn to the nanoparticles promoted the catalytic activity of Ni-Zn nanoparticles, e.g. the catalytic activity of Ni-Zn/TiO 2 for 1-octene hydrogenation was ca. 10 times higher than that of the unsupported Ni nanoparticles. Ni in the nanocomposite was assigned as metallic, although their surface was oxidized under the atmospheric condition, but Zn and B were deposited as their oxide.
