Surface modification procedure was carried out by electrochemical oxidation method at 0.0-2.0 V potential range in acetonitrile containing 0.15 M LiClO4 as a supporting electrolyte medium. The prepared modified surfaces were characterized by cyclic voltammetry, EIS, FT-IR UV-Vis and SEM/SEM-EDX techniques. Modification of surfaces was confirmed by results of characterization studies. The electrocatalytic activity of modified electrodes was investigated upon bioanalytical species like ascorbic acid, catechol, cysteine etc. It was seen that both modified electrodes showed excellent electrocatalytic activity on catechol, but the catalytic activity potential of the electrode modified with Co (II) complex was higher on the other species.eninfo:eu-repo/semantics/closedAccessSchiff Base metal complexelectropolymerizationsurface characterizationelectrocatalytic investigationConference Object493036WOS:000413538600005Q4
