Synthesis and Electrochemical Performances of Electroactive Nano Layered Organic-Inorganic Perovskite Containing Trivalent Iron Ion

Abstract:

A steady layered organic-inorganic perovskite hybrid containing Fe³⁺ was prepared in the air with phenosafranine as organic sheets, the Fe(CN)₆^3- as inorganic sheets. We utilized the Fe(CN)₆^3- as inorganic sheets of perovskite hybrids, which may help to stabilize the unusual metal-deficient layered structures. The results of X-ray diffractometry (XRD) and scanning electron microscopy (SEM) show that the hybrid is typical layered perovskite structure. The hybrid was mixed with paraffin to form a hybrid paste for the hybrid paste electrode. Electrochemical characteristics of carbon paste electrode (CPE) modified by hybrid were investigated with cyclic voltammetry. The modified electrode can accelerate the electron-transfer to improve the electrochemical reaction reversibility and be use for the determination of chemicals. The interactions between sodium nitrite (NaNO₂), sodium bromide (NaBr), hydroxylammonium chloride (NH₂OH·HCl), hydroquinone (C₆H₆O₂) with hybrid were studied. The modified electrode exhibits good electrochemical activity. The hybrid can be used as electrochemical materials.
