Single-crystalline copper sulfide (beta-Cu2S) nanocrystals (NCs) were grown in situ on multiwalled carbon nanotubes (MWCNTs) by the solvothermal method. The morphology of the Cu2S NCs was varied from spherical particles (av size = 4 nm) to triangular plates (av size = 12 nm) by increasing the concentration of the precursors. The lattice matching between Cu2S and the MWCNTs would be an important factor in the growth of Cu2S NCs on the MWCNTs. The solar cells and the amperometric glucose sensors fabricated using these Cu2S-MWCNT hybrid nanostructures respond more sensitively than those using the Cu2S NCs (or MWCNTs) alone. The utilization of the active Cu2S NCs through direct binding with the conductive MWCNTs would lead to excellent performance of these nanodevices.
