Visible light photocatalytic activity of TiO2/MWCNTS nanocomposite prepared using hydrothermal method

Titanium dioxide nanocomposites/multi-walled carbon nanotubes (TiO2/MWCNTs) were successfully synthesized by hydrothermal method. The synthesized TiO2/MWCNTs nanocomposites (10, 30 and 50% TiO2/MWCNTs) nanocomposites were characterized with powder X-ray diffraction (XRD), transmission electron microscope(TEM) and UV–visible diffuse reflection spectrum (DRS). The photocatalytic activity of TiO2/MWCNTs nanocomposite for the degradation of Rhodamin B (RhB) under visible light irradiation was studied. Compared with pure TiO2 nanoparticles, the TiO2/MWCNTs nanocomposite displayed higher photocatalytic activity for the degradation of RhB and the 30% TiO2/MWCNTs photocatalyst exhibited the highest photocatalytic activity.
