Abstract: Arc-discharge with carbon electrodes containing Ni and Y2O3 in the presenceof FeCO5 vapors have been investigated. It is found that unlike the cathodedeposit, the web deposited in the chamber contains mainly metallicsingle-walled carbon nanotubes SWNTs as evidenced from Raman and opticalabsorption spectroscopy. The percentage of metallic SWNTs increases with theconcentration of FeCO5. Under optimal conditions, the web contains over 90%of metallic SWNTs. This method enables the synthesis of nearly pure metallicSWNTs on a large scale.
