Abstract: We have successfully prepared a series of Pd-Ni/TiO catalysts by a one-step impregnation-reduction method. Among these catalysts with different compositions of Ni and Pd, the one with the Ni:Pd ratio of 2.95 showed the best activity. Small monodispersed Pd-Ni bimetallic nanoparticles were loaded on the surface of titanium oxide nanopowder as confirmed with TEM and EDS mapping. The XPS analysis demonstrated that Pd exists as 31% Pd(II) species and 69% Pd(0) species and all nickel is Ni(II). The prepared Pd-Ni/TiO exhibited enhanced catalytic activity compared to an equal amount of Pd/TiO for Suzuki-Miyaura reactions together with excellent applicability and reusability.
