Visible light-induced photocatalytic behavior of a layered perovskite-type rubidium lead niobate, RbPb2Nb3O10

Catalysis Research of Relevance to Carbon Management: Progress, Challenges, and Opportunities

“…There are limited materials that can utilize a significant portion of the visible spectrum, and progress is being made in this direction. 53 Extensive research toward the development of photocatalytic and photoelectrochemical materials that efficiently absorb visible light are being conducted. 54,55 For example, Arakawa's group split water to H 2 and O 2 stoichiometrically using mixtures of sodium carbonate with NiO x /TiO 2 and solar radiation.…”

Designed Reversible Alkylamine Intercalation–Deintercalation in the Layered Perovskite‐Type Oxide KCa2Nb3O10

“…[1] Both of these two phases can be feasibly converted into their protonated derivatives H[A m-1 B m -O 3m+1 ] and H 2 [A m-1 B m O 3m+1 ] by acid treatment. [2][3][4][5][6][7][8] These protonated layered perovskites have attracted much attention for their photocatalytic activity, [9] ion conductivity [10] and intercalation behaviour. [1,2,5] As is well-known, most layered compounds can be intercalated by organic cations or molecules to form intercalation compounds.…”

Photocatalytic Water Splitting Over a Protonated Layered Perovskite Tantalate H1.81Sr0.81Bi0.19Ta2O7

“…But hydrogen evolution was not observed from pure water in this experiment using Bi 2 SrTa 2 O 9 after 4 h of reaction time. The H + -exchanged forms are known to be easily hydrated [7,12,19,25,26]. The marked improvement of the photocatalytic activity of HST may be due to the migration of the reactant H 2 O into the interlayer spaces [25].…”
