| Abstract: | Multi-walled carbon nanotube (MWCNT)-supported tungsten trioxide (WO3) composite catalysts were prepared by liquid-phase process. WO3 nanoparticles grew on the inner and outer surface of MWCNTs. Their photocatalytic activities in the degradation of the Rhodamine B Dye were studied. The effects of mass ratio of MWCNTs to WO3 were discussed. X-ray diffraction, field emission transmission electron microscopy, thermogravimetric-differential thermal analysis and ultraviolet-visible light absorption spectra were carried out to characterize the composite catalysts. The results indicated that the optimum mass ratio of MWCNTs to WO3 is 5:100. |
