Palladium Nanoparticles Embedded in the Inner Surfaces of Carbon Nanotubes: Synthesis, Catalytic Activity, and Sinter Resistance

Abstract The highly efficient preparation of metal nanoparticles embedded in a carbon nanotube remains a considerable challenge. Herein, we report a simple and template‐based procedure for the fabrication of carbon nanotubes with Pd nanoparticles uniformly embedded in the inner carbon surfaces. In addition to the novel structure, the sinter‐resistance of the as‐prepared Pd/C nanocomposite was much better than that of the traditional carbon‐nanotube‐supported Pd catalysts. The as‐prepared Pd/C nanocomposite has a high recyclability in a liquid‐phase Suzuki coupling reaction. This strategy may be extended as a general approach to prepare metal nanoparticles supported on carbon‐nanotubes.
