A study on Cu2Co2SOD and Co2Co2SOD by voltammetry and thin-layer spectroelectrochemistry.
The electrochemistry of Co(2)Co(2)SOD and Cu(2)Co(2)SOD on a pyrolytic graphite electrode (PGE) without using mediators was investigated by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The reversible and quasi-reversible voltammetric responses were observed for Co(2)Co(2)SOD and Cu(2)Co(2)SOD, respectively. Their formal redox potentials and electron numbers involved in electrode reactions were obtained, and are in agreement with those by spectroelectrochemistry (SEC).
