Abstract

In the present study, we report for the first time synthesis of TiO 2 nanotubes/CNTs heterojunction membrane. Chemical vapor deposition (CVD) of CNTs at 650 °C in a mixture of H 2/He atmosphere led to in situ detachment of the anodically fabricated TiO 2 nanotube layers from the Ti substrate underneath. Morphological and structural evolution of TiO 2 nanotubes after CNTs deposition were investigated by field- emission scanning electron microscopy (FESEM), glancing angle X-ray diffraction (GAXRD), and X-ray photoelectron spectroscopy (XPS) analyses.
