Photocatalytic degradation of rhodamine B dye with MWCNT/TiO₂/C₆₀ composites by a hydrothermal method

Abstract

Multi-walled carbon nanotube (MWCNT)/TiO₂/C₆₀ composite catalysts were prepared by hydrothermal method. TiO₂ was deposited on the MWCNT surface. Their photocatalytic activities for degradation of Rhodamine B dye were studied. X-ray diffraction, field emission transmission electron microscopy, ultraviolet-visible light absorption spectrum and photoluminescence spectrum were carried out to characterize the composite catalysts. The results indicated that MWCNTs and C₆₀ could greatly enhance the photocatalytic activity of TiO₂.
