Abstract

High pressure high temperature catalytic method was used to prepare diamonds using carbon nanotubes or graphite as starting materials. It was found that the O-containing functional groups on diamonds' surface from carbon nanotubes (7.34%) are 1.27 times of those from graphite (5.8%), which was confirmed by Fourier transform infrared spectroscopy and x-ray photoemission spectroscopy. A small-angle x-ray scattering technique detected that the surface functional groups can combine with biochemicals. This result revealed that the as-prepared diamond might have promising application in drug delivery. © 2011 American Institute of Physics.
