Dense polyhedral nanocavities inside single‐crystalline anatase TiO 2 nanorods are successfully synthesized by simply heating H 2 Ti 3 O 7 nanorods. The size of the nanocavities is typically about 10 nm. The surfaces of the nanocavity polyhedron are determined to be the crystallographic low‐index planes of the TiO 2 crystal (see figure).
