Copper sulfide nanoribbon growth triggered by carbon nanotube aggregation via dialysis.

The growth of copper sulfide (Cu x S) nanoribbons, a class of Cu x S nanomaterials, was achieved by the aggregation of single-walled carbon nanotubes (SWCNTs) via a dialysis process. The obtained nanoribbon structure and its constituent elements on a film of SWCNT aggregates were confirmed by transmission electron microscopy (TEM) and scanning transmittance electron microscopy-energy dispersive X-ray spectroscopy. The subsequently obtained TEM images and Raman spectra revealed that nucleus synthesis and subsequent growth of Cu x S nanoribbons occurred during the aggregation of SWCNTs. The growth procedure described in this work provides an approach for the wet chemical synthesis of metal sulfide nanomaterials.
