Diamond Nanorods from Carbon Nanotubes

Diamond Nanorods from Carbon Nanotubes

The synthesis of single‐crystalline diamond nanorods (with diameters of 4–8 nm and with lengths up to 200 nm) via the hydrogen plasma post‐treatment of multiwalled carbon nanotubes is described. The diamond nanorods (see Figure) are identified as having a core–sheath structure with the inner core be...

Zusammenfassung:The synthesis of single‐crystalline diamond nanorods (with diameters of 4–8 nm and with lengths up to 200 nm) via the hydrogen plasma post‐treatment of multiwalled carbon nanotubes is described. The diamond nanorods (see Figure) are identified as having a core–sheath structure with the inner core being diamond crystal and the outer shell being composed of amorphous carbon. A growth mechanism for diamond nanorods is proposed.
