Adsorbed Monomer Effects of Central Metals

Electrocatalytic oxidation of cysteine on graphite electrodes modified with MTSPc complexes showed that the catalytic activity decreased with M as follows Co Fe Mn Ni Cu, whereas the electrocatalytic reduction of cystine 

Oxidation of 2-mercaptoethanol and other thiols on CoTAPc electropoly-merized on carbon electrodes, showed that the activity of the electrode remained similar to that of the adsorbed monomer, with the polymer showing higher stability than the monomer. The mechanisms for the catalytic oxidation of 2-ME by CoTAPc monomer or polymer were similar.
