Synthesis of carbon nanotube supported Pd catalysts and evaluation of their catalytic properties for CC bond forming reactions

A simple method of depositing Pd nanoparticles onto carbon nanotubes (CNTs) as catalyst supports is devised for CC bond forming reactions. Thiol groups were utilized as linkers to secure the Pd nanoparticles without agglomeration. The samples were characterized by TEM, XPS and Raman spectroscopy. The prepared CNT-Pd nanocomposites effectively promoted the formation of CC bonds at a low Pd content (∼2.0%) and in the absence of any ligand. This result indicates that surface thiolation is an effective way to obtain highly dispersed metal nanoparticles on the surface of CNTs and markedly improves their catalytic activity.
