Several layered perovskites $A_2Ln_2Ti_3O_{10}$ (A = K or Rb; Ln = rare earth) and their monohydrates, crystg. in tetragonal structures related to ${Sr_4Ti_3O_10}$, were prepd. The alkali ions in $K_2Ln_2Ti_3O_{10}$ are topochem. exchanged by protons in aq. acid or by other alkali ions in molten salts. $H_2Ln_2Ti_3O_{10}$ also adopt a tetragonal structure similar to the parent oxides. Dehydrated $H_2La_2Ti_3O_{10}$ crystallizes at 1000 giving a new defect perovskite, $La_2/3TiO_3$, possessing a tetragonal structure.read more

Inorganic Materials as Catalysts for Photochemical Splitting of Water
TL;DR: A review of the known inorganic catalysts with a focus on structure-activity relationships is given in this article, where the first water splitting system based on TiO2 and Pt was proposed by Fujishima and Honda in 1972.

Perovskites by Design: A Toolbox of Solid-State Reactions
TL;DR: In this paper, a set of soft-chemical reactions of layered perovskites have been reported, and they can be classified into sets of similar reactions, such as ion exchange and intercalation reactions, and more complex metathesis reactions replace interlayer cations with cationic structural units.

TL;DR: The use of selective extraction of one or more elements from the precursor materials releases 2D structures that in turn will result in expanding the world of nanomaterials in general and 2D materials in particular, generating new materials that cannot be produced by other means.

Tsuyoshi Takata,Yoko Furumi,Kiyoaki Shinohara,Akira Tanaka,Michikazu Hara,Junko N. Kondo,Kazunari Domen +6 more
TL;DR: In this paper, a series of ion exchangeable layered perovskite type oxides, A2-xLa2Ti3-xNbxO10 (A = K, Rb, Cs; x = 0, 0.5, 1.0), were found to be highly efficient photocatalysts for overall water splitting when a small amount of Ni was loaded.

Prying Apart Ruddlesden−Popper Phases: Exfoliation into Sheets and Nanotubes for Assembly of Perovskite Thin Films
TL;DR: Protonated Ruddlesden−Popper tantalates and titanotantalates H2[An-1BnO3n+1] (A = Na, Ca, Sr, La; B = Ta, Ti) were exfoliated using tetra(n-butyl)ammonium hydroxide (TBA+OH-) as mentioned in this paper.
