摘要

In this work, CuS nanotubes composed of nanoparticles with relative high catalytic activity have been successfully synthesized via a facile conversion process from ZnS nanotubes precursors. The successful chemical conversion from ZnS nanotubes to CuS ones could be attributed to a cation exchange process which benefits by the large difference in solubility between ZnS and CuS. A possible formation mechanism and growth process of the CuS nanotubes is discussed based on the experimental results. The as-prepared CuS nanotubes were then used as counter electrodes (CEs) and demonstrated good performance in dye-sensitized solar cells (DSSCs). The good performance is attributed to the increased surface area and the good electrocatalytical activity of CuS. This approach can provide a potent technique to obtain inorganic materials with unique structures and chemical compositions.
