Preparation and Characterization of Photocatalytic TiO₂/CdS Nanocomposite Loaded on Multi-Walled Carbon Nanotues (MWCNTs)

Abstract:

Multi-walled carbon nanotues (MWCNTs)/TiO2/CdS composite photocatalysts were prepared by sol–gel method in order to investigate its photocatalytic activity under simulated solar irradiation. MWCNTs/TiO2/CdS composite photocatalysts were characterized by the methods of SEM, XRD, TG and UV–vis. The results showed that MWCNTs/TiO2/CdS composites were mainly composed of anatase-TiO2 and little CdS cubic phases. the composite can cause an pronounced red shift of UV–vis spectra compared with pure TiO2. The degradation of MO by MWCNTs/TiO2/CdS composite photocatalysts under simulated solar light irradiation was studied. The results showd that the presence of MWCNTs and CdS can enhance the photoefficiency of TiO2.
