A series of carbon nanotubes/TiO_2 nanotubes(CNTs/TNTs) composite photocatalysts were successfully prepared by incorporation of CNTs in HNO_3 washing process.These photocatalysts were characterized by XRD,N_2 physical adsorption.UV-vis diffuse reflectance spectroscopy,TEM and Raman spectroscopy,respectively,and their photocatalytic activities were tested by using methyl orange(MO) as a model compound.Also,the effects of amount of CNTs incorporated,calcination temperature and amount of catalyst on the photocatalytic activity of the composite photocatalyst were systematically investigated.The results show that the CNTs/TNTs composite exhibits much higher photocatalytic activity than that of the TNTs or CNTs alone.
