Abstract

The electrochem. deposition of MoO2 at edge-plane-like sites along the surface of MWCNTs produces nanoplugs of MoO2 at the ends of the tubes, which are the regions of greatest electrochem. activity. It also speculates that it may be possible to form nanorings of MoO2 around the circumference of the nanotube. It is envisaged that, as nanotechnol. progresses, this rapid and simple method of forming nanoplugs at the ends of CNTs may be used in the fabrication of nanoelectronic circuitry. MoO2 can be easily reduced to Mo metal by heating to around 500° under a flow of hydrogen gas as the MWCNTs can withstand temps. up to around 700°. The Mo metal at the ends of the CNTs could then be used to form well-defined elec. contacts between CNTs. [on SciFinder(R)]
