Abstract
Electrocatalytic activity of the Pt microparticles dispersed into polyfuran (PFu) films on platinum (Pt), glassy carbon (GC) and graphite (Gr) electrodes towards methanol oxidation in acid medium has been investigated using cyclic voltammetry, potentiodynamic polarization and impedance spectroscopic techniques. The results show that PFu films obtained on these electrodes serve as good host matrices for the dispersion of Pt microparticles and exhibit good catalytic activity towards the electrooxidation of methanol. The maximum electrocatalytic activity was observed on Pt modified PFu films on Pt substrates followed by those obtained on GC and Gr substrates respectively.
