Abstract
Mass production of carbon nanotubes (CNTs) on an easy soluble support has been achieved by chemical vapor deposition method. CNTs have been synthesized using nickel formate as catalyst precursor at 700˚ C. The structure of the grown product was characterized by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy and X-ray diffraction method. The purity of as grown product and purified product was determined by thermal analysis. The yield of CNTs was up to 8300 wt% relative to the catalyst have been achieved in the growth time of 15 mins. The purified product was decorated by palladium nanoparticles by solventless method. The palladium decorated CNTs were characterized by scanning electron microscope and X-ray diffraction method. The ad vantages of these routes are the simplicity and use of easily available low cost precursors. The hydrogenation behaviour of purified and decorated carbon nanotubes was carried out at room temperature and 90 bar pressure, using a high pressure Sieverts apparatus.
