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

Abstract

The method of cyclic voltammetry (CV) was used to compare electrochemical and electrocatalytic properties of meso-triphenylcorrole [H3(ms-Ph)3Cor] 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.
