Synthesis and activity of the Pt catalyst supported on CNT

Carbon nanotubes (CNT) were obtained by the decomposition of methane on a Ni catalyst supported on Al2O3. After the removal of the catalyst materials from CNT, a CNT-supported Pt catalyst was prepared, and this catalyst was characterized by XRD, XPS, and TEM. Activity of the CNT-supported Pt catalyst for hydrogenation of carbon–carbon double bonds at room temperature under the atmospheric pressure of hydrogen was examined. The CNT-supported Pt catalyst showed higher activity than the commercial Pt catalysts supported on activated carbon.
