We demonstrate a simple purification method of carbon nanotubes via sulfidation reaction of carbon, C + 2S → CS<sub>2</sub>, to selectively remove carbonaceous impurities from nanotubes. The sulfidative purification of <i>carbon nanotubes integrated in field-effect transistors</i> results in a dramatic improvement of switching characteristics due to removal of carbonaceous impurities.
