Well-aligned CuCl nanorods standing on a Si substrate were prepared via evaporation of CuCl powder in vacuum. Using these CuCl nanorods as a precursor, arrays of CuS nanotubes with diameters in the range 150–250nm and lengths up to several micrometers have been successfully obtained through a gas-solid sulfurization reaction. Scanning electron microscopy indicates that the morphology and orientation...
