Direct Synthesis of Anatase TiO2 Nanowires with Enhanced Photocatalytic Activity

IO N Nanostructured materials with controlled shapes and structures have drawn considerable attention for both fundamental research and practical applications. [ 1–5 ] Particularly, onedimensional (1D) nanostructures such as nanowires, nanorods, and nanotubes are of great importance owing to their unique physicochemical properties and anisotropic structures. [ 6–9 ] 1D nanostructures of a wide variety of materials have been successfully synthesized, including carbons (e.g., carbon nanotubes [ 10 ]
