Synthesis and Characterization of Titania Nanotube-Carbon Nanotube Composite for Degradation of Phenol

Desi Heltina, Praswasti PDK Wulan, Slamet Slamet

 

Abstract:

Titania
nanotube (TNT)-carbon nanotube (CNT) composite had been successfully
synthesized using simple mixing under acidic conditions and ultrasonic treatment. The samples were further characterized via field emission scanning electron microscopy (FESEM), X–ray
diffraction (XRD), diffuse reflectance UV-vis spectroscopy, and Brunauer-Emmett-Teller (BET) analysis. The TNT–CNT
composite’s ability to degrade phenol, a model of industrial waste, was tested. The effects of CNT composition and calcination temperature on the phenol degradation performance
of TNT-CNT composite were investigated. The
results show that the TNT-CNT composite exhibits higher photocatalytic activity
than TNT or CNT alone. The crystallinity of the catalyst is not the only parameter
affecting the photocatalytic activity. Rather, the specific surface area, bandgap, and morphology of the catalyst must also be considered.

Keywords: Degradation; Phenol; Photocatalysis; Titania nanotube - Carbon nanotube composite
