Fluorite‐structured CeO 2 nanotubes have been synthesized by controlled annealing of layered Ce(OH) 3 nanotubes. The latter have been fabricated by means of hydrothermal treatment of anhydrate cerium chloride. The Ce(OH) 3 nanotube formation has been attributed to lamellar rolling under appropriate conditions. The non‐layered CeO 2 could possess nanotubular morphology only in the presence of structural defects (see Figure; tube diameter: ∼ 18 nm).
