A series of CNT-TiO2 composite photocatalysts was successfully prepared by dispersing carbon nanotubes using surfactants (CTAB and cocoPAS). Composites are characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared absorption spectroscopy (FTIR), Breuneur Emmet Teller (BET) and diffuse reflectance UV-vis spectroscopy. The purpose of this study were synthesize TiO2-CNT composite using surfactant and evaluate its performance for photodegradation phenol. The catalytic activity of this composite material was investigated by composite applications for phenol degradation. The as-prepared nanotubes, with surfactant contents, showed high- photocatalytic activities with increase degradation. [ABSTRACT FROM AUTHOR]

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]
