Photocatalytic property of Ag modified nano-TiO2/carbon nanotube composites for NO2 degradation under visible light

摘要

The photocatalytic property for NO2 degradation under visible light was improved through Ag modification and multiwalled carbon nanotubes (MWCNTs). Test results showed that the combined efficacy of Ag and MWCNTs was much larger than the efficacy of MWCNTs, and Ag and carbon nanotube had a synergistic effect on nano-TiO2 when they are doped together. Moreover, the enhancement mechanism was analysed through ultraviolet-visible and SEM methods.
