摘要

A novel method for the fabrication of a TiO_2/Nafion nano-film on glassy carbon electrode (NTGCE) is described. In the presence of dispersant, TiO_2 nanoparticles were dispersed into water to give a homogeneous and stable suspension. After the solvent evaporation, a porous and uniform TiO_2 nano-film was obtained on the GCE surface. Further coated with Nafion, the complex film possesses remarkable stability in aqueous solution. This nano-film was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The prepared electrode showed excellent electrocatalytic behavior of dopamine and high concentration of ascorbic acid does not interfere with the dopamine detection. Based on this, an electrochemical method is developed for the determination of dopamine with simplicity and high sensitivity.
