Abstract
Filled carbon nanotubes (CNTs) and methods of synthesizing the same are provided. An in situ chemical vapor deposition technique can be used to synthesize CNTs filled with metal sulfide nanowires. The CNTs can be completely and continuously filled with the metal sulfide fillers up to several micrometers in length. The filled CNTs can be easily collected from the substrates used for synthesis using a simple ultrasonication method.
Claims20
A compound comprising:
- a plurality of carbon nanotubes (CNTs);
- and
- a nanowire of a metal sulfide respectively filled in each CNT,
- an average filling ratio, across all of the CNTs present in the compound, of the metal sulfide being at least 0.90,
- the CNTs having an average length of at least 5 μm,
- each CNT filled with the respective nanowire being straight from a first end thereof to a second end thereof, and
- the first end and the second end of each CNT filled with the respective nanowire being closed with carbon shells.
