Complex layered perovskite-like oxides ALnTiO₄, A₂Ln₂Ti₃O₁₀, ALnNb₂O₇, ALnTa₂O₇ (A - Li, Na, K, Rb, Cs, H; Ln - La, Nd) are crystalline compounds where layers of the perovskite structure are alternating with layers having different type of structure. Recently, the said phases have attracted significant attention due to their photo-catalytic properties [1, 2]. They can also be used as precursors to obtain other perovskite-like compounds by means of ion exchange or certain topochemical transformations. It was found that alkaline forms of such perovskites in the aqueous medium can perform replacement of cations by protons and hydration (rooting of water molecules in the interlayer space). These effects lead to substantial changes in physical and chemical properties of photo-catalysts. The composition of layered perovskite oxides may include several different metals [1-5], and depending on their nature and stoichiometry, these objects can display a wide range of physical and chemical properties. Normally, perovskite-like oxides are semiconducting materials.
