Pd-Ni nanoparticles supported on titanium oxide as effective catalysts for Suzuki-Miyaura coupling reactions

Dongxu Han, Zhiguo Zhang, Zongbi Bao, Huabin Xing, Qilong Ren

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 1,   Pages 24-31 doi: 10.1007/s11705-017-1669-4

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.

Frontiers of Chemical Science and Engineering 2010, Volume 4, Issue 1,   Pages 52-56 doi: 10.1007/s11705-009-0301-7

Abstract: In this paper, the research framework for specific structure crystallization modeling has been proposed in which four steps are required in order to investigate the rigorous crystallization modeling by thermodynamics. The first is the activity coefficient model of the solution, the second is Solid-Liquid equilibrium, the third and fourth are the dissolution and crystallization kinetics modeling, respectively. Our investigations show that the mechanisms of complex structure formation and microphase transition can be analyzed by combining the dissolution and crystallization kinetics modeling. Moreover, the formation mechanism of the porous KCl has been analyzed, which may provide a reference for the porous structure formation in the advanced material synthesis.
