Synthesis of Pd–CNT nanocomposites and investigation of their catalytic behavior in the hydrodehalogenation of aryl halides

A catalytic system based on Pd–CNT nanocomposites for the hydrodehalogenation of aryl halides is described. Thiol groups were utilized as linkers to secure the Pd nanoparticles without agglomeration. The Pd–CNT nanocomposites effectively promoted the hydrodehalogenation of aryl halides at a low Pd content (∼2.3%) and in the absence of any ligand. The results suggest that the CNTs could significantly influence the catalytic activities of CNT-supported metal catalysts for hydrodehalogenation.
