The nanostructured materials (Q(8)M(8)(H) and EsFc) were characterized by Fourier transform infrared spectra (FT-IR), nuclear magnetic resonance (NMR), X-ray diffraction (XRD), Thermogravimetric analyses and Voltammetric technique The cyclic voltammograms of the graphite paste electrode modified with ESFc showed one redox couple with E-0' = 0.320 V (1.0 mol L-1 NaCl, v = 50 mV s(-1)), with a diffusion-controlled process and the redox process shows electrocatalytic activity for the oxidation of ascorbic acid.
