摘要
Carbon nanotubes with diameters ranging between 140～220nm was synthesized with chemical vapor deposition method, and treated using nitric acid as oxidant. Pt/C catalysts were prepared using untreated and treated carbon nanotubes as supports, respectively. TEM and FT IR differential spectra showed that treated carbon nanotubes become short and possess more oxygen containing surface groups. The electrochemical studies indicated that the Pt/treated carbon nanotubes catalyst possessed much higher electrocatalytic activity for the oxidation of methanol than that of the Pt/untreated carbon nanotubes catalyst.
Carbon nanotubes with diameters ranging between 140 similar to 220nm was synthesized with chemical vapor deposition method, and treated using nitric acid as oxidant. Pt/C catalysts were prepared using untreated and treated carbon nanotubes as supports, respectively. TEM and FT-IR differential spectra showed that treated carbon nanotubes become short and possess more oxygen-containing surface groups. The electrochemical studies indicated that the Pt/treated carbon-nanotubes catalyst possessed much higher electrocatalytic activity for the oxidation of methanol than that of the Pt/untreated carbon-nanotubes catalyst.
