Photocatalytic Activity of Titania Nanotube (Tint)-Carbon Nanotube (CNT) Composite for Degradation of Phenol.

In this study, a composite of titania nanotube (TiNT)-carbon nanotube (CNT) was synthesized using a method of mixing . The titania nanotube–carbon nanotube composite is applied to increase the photocatalytic activity for phenol degradation. The titania nanotube–carbon nanotube composites were characterized by x-ray diffraction (XRD), scanning electron microscope (SEM), UV-vis diffuse reflectance spectroscopy and spectrophotometer. The presence of carbon nanotube on composite have a beneficial effect on photocatalytic performance titania nanotube (TiNT) a marked increase in the photocatalytic degradation of phenol. The results show that the highest activity nanocomposite sample is observed for CNT load 2 wt.%. For this purpose, a morphology of the nanocomposites and crystalline phases investigated. The photocatalytic activity composite of TiNT – CNT for phenol degradation was afterward evaluated and discussed. [ABSTRACT FROM AUTHOR]
