A simple, inexpensive gas phase reaction termed as “nanocarving process” converts TiO₂ grains into arrays of single crystal nanofibers by selective and anisotropic etching. This process is conducted by exposing dense polycrystalline TiO₂ to a hydrogen-bearing environment. This article reviews the syntheses, properties, and kinetic mechanisms of TiO₂ nanofibers via nanocarving process.
