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.
