Abstract
Layered perovskite-like oxides ANdTa2O7 (A = H, Li, Na, K, Rb, Cs) were synthesized and characterized by means of diffuse reflection spectroscopy, thermogravimetry, and simultaneous thermal and X-ray phase analysis. Comparative analysis of the photocatalytic activity of ANdTa2O7 in the UV-induced hydrogen evolution from an aqueous isopropanol solution was performed. NaNdTa2O7 and HNdTa2O7 are able to intercalate water to the interlayer space. The compositions and thermal stability ranges of intercalates were determined. No explicit correlation between the photocatalytic activity of layered oxides and their ability to intercalate water to the interlayer space was found.
