Non-stoichiometric titanate CsィイD2xィエD2TiィイD22-x/4ィエD2OィイD24ィエD2 is a layer structured compound with the lepidocrocite (FeO(OH)) related structure. CsィイD1+ィエD1 in the interlayer space of CsィイD20.68ィエD2TiィイD21.83ィエD2OィイD24ィエD2(x=0.68 in CsィイD2xィエD2TiィイD22-x/4ィエD2OィイD24ィエD2) is quantitatively ion exchanged with hydrated HィイD1+ィエD1, LiィイD1+ィエD1 and NaィイD1+ィエD1 using aqueous solutions. The ionic conductivities of the products are comparable to those of the layered clay minerals of vermiculite and montmorillonite in which mobile cations are hydrated. Interlayer CsィイD1+ィエD1 ions are also ion exchanged with transition metal ions of NiィイD12+ィエD1, CuィイD12+ィエD1 and CoィイD12+ィエD1 through LiィイD1+ィエD1 exchanged product. These products were characterized by UV-VIS-NIR measurement.

非化学计量比钛酸盐CsィイD2XィエD2TiィイD22-x/4ィエD2OィイD24ィエD2是一种层状结构的化合物，具有与FeO(OH)相关的结构。CsィイD20.68ィエD2TiD21.83ィエD2OィイD24ィエD2(x=0.68in CsィイD2XィエD2TiィイD22-x/4ィエD2OィイD24ィエD2)与水合HィイD1+ィエD1、LiィイD1+ィエD1和NaィイD1+ィエD2在水溶液中进行了定量离子交换。产物的离子电导率与水合活泼阳离子的蠕石和蒙脱石层状粘土矿物的离子电导率相当。层间CsィイD 1+ィエD 1离子还通过LiィイD 1+ィエD 1交换产物与过渡金属离子NiィイD12+ィエD 1、CuィイD12+ィエD 1和CoィイD12+ィエD 1进行离子交换。用紫外-可见-近红外光谱对产物进行了表征。
