A facile one-pot strategy for the electrochemical synthesis of poly(3,4-ethylenedioxythiophene)/Zirconia nanocomposite as an effective sensing platform for vitamins B2, B6 and C.

Highlights: [•] PEDOT/ZrO2NPs nanocomposite film was synthesized by one-step polymerization. [•] ZrO2NPs could improve the electrical and catalytic properties of PEDOT. [•] The modified electrode showed high electrochemical activity for VB2, VB6 and VC. [•] The modified electrodes were applied to simultaneous determination of VB2, VB6 and VC. [•] The method was successfully applied to detect VB2, VB6 and VC in practical sample. [Copyright &y& Elsevier]
