Abstract

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.
