Abstract:The composite of carboxyl-modified multi-walled carbon nanotubes (MWNT-COOHs) and TiO2 nanoparticles was prepared by improved solvothermal process. X-ray diffraction (XRD), transmission electron microscope (TEM) and UV-Vis spectra were used to characterize the products. The results show that MWNT-COOHs were “welded” by the TiO2 nanoparticles attached to the open ends of MWNT-COOHs. Compared with pure TiO2 nanoparticles, the composite displays higher photocatalytic activity with 99.9% of degradation ratio of copper sulfophthalocyanine after 3 h irradiation.
Keywords:Carbon nanotube  TiO2 nanoparticles  composite  photocatalysis
