摘要：

Anionic clays Zn2Cr(OH)(6)Cl . 2H(2)O, denoted [Zn-Cr-Cl], and Zn3Al(OH)(8)Cl . 2H(2)O, denoted [Zn-Al-Cl], are rapidly exchanged with electroactive organic sulfonate anion such as 2,2'-azinobis 3-ethylbenzothiazoline-6-sulfonate (ABTS). These samples are prepared by a simple exchange reaction or by the coprecipitation method. High degrees of exchange are obtained and pillar-like layered structures are formed. Clay-carbon paste modified electrodes have been produced using these materials and the precursor [Zn-Cr-Cl]. The electrochemical behaviour of the intercalated substrate has been studied using cyclic voltammetry. The electrogenerated radical of intercalated [Zn-Al-ABTS] has been characterized by EPR.
