摘要

The direct growth and electrochemical (EC) properties of multiwalled carbon nanotubes (MWNTs) on Ti foil have been investigated. The EC properties of MWNTs were probed before and after HNO₃ treatment. Cyclic voltammograms (CVs) of HNO₃-treated MWNTs showed reversible electron transfer properties. In contrast, the CVs of untreated MWNTs became unstable when the scan rate exceeded 80 mV/s. The transmission electron microscopy image shows the tip of the MWNT is opened after HNO₃ treatment. The stabilization of CVs for treated MWNTs could be due to the faster charge transfer through the graphite edge planes of open tips.
