Multiwalled Carbon Nanotubes with Molybdenum Dioxide Nanoplugs—New Chemical Nanoarchitectures by Electrochemical Modification

Electrochemically plugged: Here we report a novel type of nanoarchitecture that consists of nanoplugs of MoO2, a conducting transition-metal oxide, formed at edge-plane-like sites on the ends of carbon nanotubes (see SEM image). By using a facile and rapid electrochemical deposition technique, this startling and beautiful example of electrochemically controlled nanoarchitecture with potential future applications in nanoelectronic circuitry is shown.
