摘要：

We demonstrate that graphite powder and multiwalled carbon nanotubes (MWCNTs) can be derivatised by 4-nitrobenzylamine (4-NBA) simply by stirring the graphite powder or MWCNTs in a solution of acetonitrile containing 10 mm 4-NBA. We propose that 4-NBA partially intercalates at localised edge-plane or edge-plane-like defect sites and support this hypothesis with a range of experimental data provided by electrochemistry in both aqueous and nonaqueous, media, electron microscopy and X-ray powder diffraction.
