Multi-walled carbon nanotubes with controllable structures are produced at a low temperature (175 °C) by using CCl4 as the precursor for pyrolytic growth in a supercritical carbon dioxide medium, in the presence of iron catalysts encapsulated in polypropyleneimine dendrimers (see picture). This work may lead to a large-scale, cost-effective synthesis of carbon nanotubes for practical applications.
