A Pd catalyst supported by single-walled carbon nanotubes (SWNTs) was prepared by a redox reaction between SWNTs and PdCl2 solution. The supported catalyst was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and thermo-gravimetric (TG) techniques. Results showed that large quantities of Pd particles with diameters of ca 2 nm distributed evenly on the surface of SWNTs and the content of Pd was 14.13% (w, mass fraction) when using SWNTs and 12 mmol·L-1 PdCl2 as reactants. The supported catalyst, after reduction by H2, exhibited high catalytic activity in Suzuki reaction. The yield of biphenyl was 98.10% after 30 min reaction at 90 ℃.
