Description

We have synthesyzed Cu and Fe- doped TiO2 nanotubes by an anodization method. The electrolyte was composed of ethylene glycol (EG), ammonium fluoride (0.3 % wt NH4F) and deionized water (2% vol H2O) with concentration of the dopants Cu and Fe of 0.5 mM. A constant DC power supply of 50 V was used during anodization with anodizing times of 2 hours. X-ray diffraction (XRD) was used to examined the microstucture and scanning electron microscopy (SEM) was used to viewed the surface morphology of the samples. The results show that TiO2 nanotubes are are anatase phases and the nanotubes are arraged in highly ordered arrays. The transition metal ion dopants may be incorporated into the TiO2 structure.
