摘　　要：以酚藏花红为有机层、以含三价铁的Fe(CN)63-为无机层,在空气中,合成层状有机-无机类钙钛矿杂合物.利用扫描电镜(SEM)和X-射线衍射(XRD)对其表面形貌和微观结构进行表征.利用循环伏安法研究了杂合物修饰碳糊电极的电化学性能,并探讨了NaNO2、NaBr、对苯二酚、盐酸羟胺与合成的杂合物相互作用.结果表明:合成的杂合物具有典型的层状结构,具有良好的电化学活性,可进一步电化学器件应用研究.A steady layered organic-inorganic perovskite hybrid containing Fe3＋ was prepared in the air with phenosafranine as organic sheets,the Fe（CN）3-6 as inorganic sheets.The morphology and microstructure of hybrid were characterized by SEM and XRD.Electrochemical performances of carbon paste electrode modified by hybrid were investigated with cyclic voltammetry.The interactions between NaNO2,NaBr,hydroquinone,hydroxylamine hydrochloride with hybrid were studied.The results show that the structure of hybrid is typical layered perovskite type.The hybrid shows good electrochemical activity,and can be used as electrochemical materials.
