A novel metal nanoparticle synthesis method has been developed, in which metallic Ni nanoparticles with an amorphous-like structure were selectively deposited on TiO₂ fine particles through the reduction from the liquid phase. The addition of Zn proved to decrease the nanoparticles size, leading to the increase in the total area of catalytically active Ni surface. In addition, nanoparticles were highly stabilized by the deposition on TiO₂, so that the catalytic activity of Zn-added TiO₂-supported Ni nanoparticles (Ni-Zn/TiO₂) in the 1-octene hydrogenation was ca. 10 times higher than that of unsupported Ni nanoparticles.
