Optimal conditions were found for the formation of carbon-oxide composites by the treatment of mixtures
of oxides of aluminum or titanium with carbon nanotubes and nanofibers in a planetary ball mill.
The dependences of the electrical conductivity of composites on the content of carbon nanomaterials (1-5%
by mass) were determined. It is shown that the addition of 3%(wt) of CNT to the oxides leads to a sharp increase
in the electrical conductivity: from 5.0×10-8 to 2.8×10-4 S/cm for Al2O3 and from 5.0×10-6 to 2.2×10-2
S/cm for TiO2. It was shown that the carbon-oxide composites are promising carriers of the catalysts of
electrode processes in electrochemical devices. It was revealed that Pt/TiO2 - CNT catalyst containing 5%
(mass) of carbon nanotubes has the best catalytic activity in oxygen reduction, in an electrode-modeling
cathode of a fuel cell.
