Title: Stability of Ruddlesden–Popper-structured oxides in humid conditions

Abstract

Some of layered transition-metal oxides are known to react with atmospheric humidity to form through topotactic intercalation reactions new water-containing layered structures. Here we investigate the influence of oxygen content (7−δ) of the Ruddlesden–Popper-structured Sr{sub 3}FeMO{sub 7−δ} (M=Ni, Mn, Ti) oxides on the water-intercalation reaction. It is found that their oxygen contents influence greatly the reactivity of the phases with water. Other factors possibly affecting the reactivity are discussed on the basis of the present data in combination with a comprehensive review of previous works on Ruddlesden–Popper and related layered oxide phases. - Graphical abstract: Many of the Ruddlesden–Popper-structured A{sub 3}B{sub 2}O{sub 7−δ} oxides readily react with water via intercalation reactions. Three possible factors affecting the water intercalation are identified: oxygen content of the phase, ionic radius of cation A and valence state of cation B. The resultant layered water-derivative phases can be categorised into two groups, depending on the crystal symmetry of the phase. Highlights: • Ruddlesden–Popper oxides A{sub 3}B{sub 2}O{sub 7−δ} often accommodate water via intercalation reaction. • The lower the oxygen content 7−δ is the more readily the intercalation reaction occurs. • The second factor promoting the reaction is the large size of cation A. • Themore » third possible factor is the high valence state of cation B. • Resultant water-derivatives can be categorised into two groups depending on symmetry.« less
