Preparation and characterization of photocatalytic TiO2/CdS nanocomposite loaded on Multi-walled carbon nanotues (MWCNTs)

摘要

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.
