Abstract
AbstractCarbon nanotubes decorated with ultra‐small metal nanoparticles are of great value in catalysis. We report that individual multiwalled carbon nanotubes decorated with ultra‐small palladium nanoparticles can be detected by using the nano‐impacts method. The high conductivity and reactivity of each decorated carbon nanotube is directly evidenced; this is achieved through studying the proton‐reduction reaction for the underpotential deposition of hydrogen onto the nanoparticles decorated on the carbon nanotube walls. The reductive spikes from current amplification are analyzed to estimate the approximate length of the decorated carbon nanotubes, revealing that the decorated carbon nanotubes are electroactive along its entire length of several micrometers.
