The electrochemical behavior and ability of a carbon paste electrode modified with iron(III)tetracyanophenylporphyrin chloride (FeTCPP-Cl) as a potential electrocatalyst for the reduction of dioxygen to hydrogen peroxide was investigated using cyclic voltammetry (CV), dou ble-potential step chronoamperometry, and hydrodynamic voltammetry at the rotating disk electrode. The modified electrode showed an excellent electrocatalytic behavior, with respect to reduction of dioxygen in acidic aqueous solu - tions with an overpotential of 750 mV lower than that at the blank carbon paste electrode. Some kinetic parameters for the process were determined from the RDE voltammetry experiments using the Koutecky-Levich plot analysis. Based on the results obtained, a mechanism of the electrocatalysis was proposed.
