Abstract

Going down the tubes: The rapid uptake of ¹³⁷Cs⁺ ions in sodium trititanate nanofibers (T3NF; see picture) and nanotubes (T3NT) triggers a phase transition or deformation of the thin titanate layers. Ag ₂O nanocrystals (5-10 nm) were bound to the surface of the nanostructures and efficiently captured I^- anions (ca. 4.5 mmol per gram of sorbent) from aqueous solutions by forming an AgI precipitate on the titanates.
