    Abstract

    In this paper we describe a new method to fabricate TiO2@C core-shell nanofiber arrays for electrochemical sensing. The TiO2@C nanofiber arrays have been produced directly on titanium surface under acetone vapor at 800 ℃. This TiO2@C core-shell nanofiber arrays have the 40 nm TiO2 core in diameter and 5-10 nm carbon shell in thickness and show good electrochemical behaviors. The cyclic voltammogram in 1.0 × 10-3 mol/L K3Fe(CN)6 is quasi-reversible. The amperometric response increases linearly with the increase of the concentration of dopamine in the range of 1.0 × 10-7 - 1.0 × 10-4 mol/L. The detection limit (S/N=3) of dopamine is 2.45 × 10-8 mol/L.
