Photocatalytic degradation and antimicrobial applications of F-doped MWCNTs/TiO₂ composites

Spectrochim Acta A Mol Biomol Spectrosc. 2015 Mar 15:139:290-5. doi: 10.1016/j.saa.2014.12.061. Epub 2014 Dec 27.

Abstract

Multi-walled carbon nanotubes-fluorine-co-doped TiO2 composite was synthesized by the solid state method. The prepared photocatalysts were characterized by using XRD, FTIR and FE-SEM. In addition, the samples were evaluated for antimicrobial activity and photocatalytic activity. The composites exhibited enhanced absorption properties in the UV light range compared to pure TiO2. The MWCNTS-F-co-doped TiO2 composites showed significant photocatalytic activity in the generation of oxygen.

Keywords: Antimicrobial activity; Fluorinated; MWCNTs; Photocatalytic activity; Titanium dioxide.
