Preparation and electrochemical properties of a noncovalent nanohybrid of ferrocene (Fc) with multi wall carbon
nanotubes (MWCNTs) on carbon-ceramic electrode (CCE), Fc-MWNT/CCE, have been investigated in an aqueous
solution in detail. One pair of surface-confined redox waves corresponding to the couple of Fc/Fc+ is obtained, which
indicates that Fc encapsulated inside MWCNTs retains electrochemical activity. It shows excellent mediation of
hydrazine (H2H4) based on Fc/Fc+ used as electron-transfer mediators for oxidation of H2H4, suggesting specific
properties of Fc-MWCNT due to a combination of Fc and MWCNT. A Fc-MWCNT/CCE-based sensor for H2H4 with a
determination limit of 0.18 μM is fabricated, and it shows good stability and reproducibility.
