Abstract

Multicomponent metallic residual catalyst impurities, which are present within carbon nanotubes even after their purification with mineral acid, are responsible for the observed "electrocatalytic" oxidation of hydrazine on carbon nanotubes. We demonstrate that in the case where multicomponent Co/Mo/Fe impurities are present within double-walled carbon nanotubes (DWCNTs), all three impurity components govern the electrochemical response of DWCNTs toward the oxidation of hydrazine.
