摘要：

In this work, palladium complexes nanoparticles in titania are prepared by a pH-controlled adsorption and without pH-controlled adsorption method. This method results in high-dispersion palladium on the titania surface. We demonstrate the use of the titania-supported palladium as an efficient catalyst for Suzuki and Heck reactions of a representative range of aryl bromides and chlorides. The reusability of catalyst was tested, and deactivation process of the catalyst was not observed after four recycles. The catalysts were characterized by FT-IR, NMR, elemental analysis, field emission scanning electron microscopy, transmission electron microscopy and X-ray diffraction.
