| Abstract: | Composite photocatalysts(TiO2/MWCNTs)with TiO2 nano-particles attached on mutil-walled carbon nanotubes were prepared using sol-gel method under various conditions.Azo dye methyl orange was selected as the model pollutant to evaluate the effect of different preparation conditions of the composite photocatalysts on the photodegradation kinetics of methyl orange.Characterization of the TiO2/MWCNTs showed that nano-TiO2 was evenly coated on the surface of the multi-walled carbon nanotubes.The crystal of nano-T... |
