Electrochemical Transfer at Anionic Clay Modified Electrodes. Case of 2,2‘-Azinobis(3-ethylbenzothiazoline-6-sulfonate)

The electrochemical behavior of the 2,2‘-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), a reversible redox probe, has been examined after it has been intercalated into the interlayer spacing of anionic clays (also called layered double hydroxides, LDH). The cyclic voltammetry response of [Zn-C...

Description
Summary:The electrochemical behavior of the 2,2‘-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), a reversible redox probe, has been examined after it has been intercalated into the interlayer spacing of anionic clays (also called layered double hydroxides, LDH). The cyclic voltammetry response of [Zn-Cr-ABTS] and [Zn-Al-ABTS] LDHs modified electrodes was compared to that obtained with ABTS adsorbed species on [Zn-Cr-TA] and [Zn-Al-TA] LDHs where TA = terephthalate anion. The stable radical ABTS•+ intercalated in the LDHs structure was studied by UV−visible spectroelectrochemistry.
