In this work, the synthesis of Pd nanoparticles/FCNTs catalyst hybrids has been achieved by spontaneous deposition in alcohol-water solution at room temperature. In the presence of carboxyl group functionalized multi wall carbon nanotube (FMWCNT) and functionalized single wall carbon nanotube (FSWCNT), Pd nanoparticles (PdNPs) were in situ generated from H2PdCl4 aqueous solution, without any additional reducing agent or irradiation treatment, and readily attached to the FCNTs surfaces, leading to the PdNPs/FMWCNT and PdNPs/FSWCNT nanohybrids. In this process, PdCl42- ions were spontaneously reduced though a galvanic cell effect between them and the FCNTs. The prepared nanohybrids were characterized by scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDX) techniques.
