By surface organic synthesis a Fe(Ⅲ)tetra-o-aminophenyl porphyrin modified electrodewas successfully prepared on glassy carbon electrode surface through amidization.The preparativeconditions were investigated in detail.Using cyclic voltammetry and semidifferential neo-polarogra-phy in an acidic aqueous solution the behavior of the catalytic reduction ofoxygen on iron porphyriamodified electrode was studied.Based on experimental results it was shown that the irreversibleprocess of 2-electron-reduction to hydrogen peroxide belongs to EC parallel catalytic process.
