dc.description.abstractTHE M(II)/(I) FORMAL POTENTIAL OF MN4 MACROCYCLIC COMPLEXES DICTATES THEIR ELECTROCATALYTIC ACTIVITY FOR MANY REACTIONS AND L-CYSTEINE OXIDATION IS NOT AN EXCEPTION. IN THIS WORK WE REVIEW THE LITERATURE RELATED TO THIS REACTION AND PROPOSE A SEMI-EMPIRICAL MODEL THAT CAN DESCRIBE THE CATALYTIC ACTIVITY OF THESE CHELATES IN TERMS OF THEIR FORMAL POTENTIAL. A CORRELATION OF LOG I (AT CONSTANT POTENTIAL) VERSUS THE M(II)/(I) FORMAL POTENTIAL FOR M= FE,CO) OF THE CATALYSTS GIVES A VOLCANO CURVE. OUR RESULTS CLEARLY SHOW THAT THE M (II)/(I) FORMAL POTENTIAL OF N4-MACROCYCLIC COMPLEXES NEEDS TO BE ADJUSTED TO VALUES AROUND -1.0 V VS. SCE TO OBTAIN THE HIGHEST CATALYTIC ACTIVITY FOR THE OXIDATION OF L-CYSTEINE. WHEN COMPARING CHELATES OF DIFFERENT METALS (M= CR, MN, FE, CO) OF TETRASULPHONATED PHTHALOCYANINES ONLY A LINEAR CORRELATION IS OBTAINED.
