  Abstract:  The obtaining of composite glassy carbon modified electrodes based on a conducting polymer (polyaniline, PANI) matrix entrapping a polynuclear inorganic compound (Prussian Blue, PB) with redox properties is reported. The electrocatalytic activity towards H2O2 reduction of PB+PANI modified glassy carbon electrodes and their electrochemical stability were studied and compared to those of PB modified electrodes prepared through simple electrodeposition of the inorganic compound onto glassy carbon (GC/PB). It was confirmed that the GC/PB+PANI modified electrodes present stable electrochemical behavior and showed good electrocatalytic efficiency for H2O2 reduction.
