Abstract :
The stability of anatase phase up to 1000°C by the process of carbon nanotubes (CNTs) - hybridization is discussed in this study. The pinning effect between TiO2 and CNTs is discovered and inhibits the nucleation of rutile phase. X-ray diffraction (XRD) and X-ray absorption near edge structure (XANES) are used to identify the phase of the nano hybrid TiO2/CNTs material. Raman spectra were used to study the first order signals of multi-wall carbon nanotubes. The structure morphology was analyzed by transmission electron microscopy (TEM).
