Electrocatalysis of chloroacetic acids (mono-, di- and tri-) at a C60-[dimethyl-(beta-cyclodextrin)]2 and nafion chemically modified electrode.
The C(60)-[dimethyl-(beta-cyclodextrin)](2) and nafion chemically modified electrode (CME) exhibits one electroreduction peak and two electro-oxidation peaks in a mixed solvent of water and acetonitrile (3:2, v/v) containing tetra-butylammonium perchlorate. The reduction of chloroacetic acids (mono-, di- and tri-) can be electrocatalyzed at this electrode, indicating that C(60)-[dimethyl-(beta-cyclodextrin)](2) is capable of mediating the electron transfer to chloroacetic acids. Values of the apparent catalytic rate constant, k, were determined by using the rotating-disk electrode (RDE).
