Electrochemical and electrocatalytic properties of meso-triphenylcorrole and its complexes with Mn(III), Co(III), Cu(III), and Zn(II)

The method of cyclic voltammetry (CV) was used to compare electrochemical and electrocatalytic properties of meso-triphenylcorrole [H-3(ms-Ph)(3)Cor] and also its complexes with Mn(III), Co(III), Cu(III), and Zn(II) in 0.1M KOH. Metal-localized redox transitions are detected in the complexes of Mn (III -> IV) and (III -> II), Co (III -> II), Cu (III -> II). It is shown that the manganese complex features most effective catalytic properties in the reaction of molecular oxygen electroreduction.
