Nonenzymatic Glucose Electrochemical Oxidation Based on Pt Decorated MWCNTs-PVA Hybrid Electrode

Abstract:

The multi-walled carbon nanotubes (MWCNTs) /polyvinyl alcohol (PVA) coating may have excellent biocompatibility and unique electrical properties. The effect of the dispersing agent on the electrochemical behaviors is very relevant,which has a great influence on the ionic conductivity of the composite material.We prepared four membrane electrodes of MWCNTs by using two dispersing processes of electrophoretic deposition (EPD). The scanning electron microscope (SEM) graphs of the MWCNTs/PVA composite were recorded In the NaOH solution, glucose is electrochemically oxidized on the acidified-MWCNTs/ PVA composite coating with high current density. The MWCNTs of the covalent dispersing methods treatment have a positive influence for the oxidation of glucose. The PVA can strengthen the dispersion effect of CTAB-MWCNTs for the EDP. The cooperative electrocatalytic property of MWCNTs-Pt toward glucose is not impaired by the association with the PVA binder.
