Abstract:A nano-composite consisting of TiO2–CNT was prepared via the sol–gel technique by using titanium n-butoxide along with carbon nano-tubes (CNTs) followed by calcination at 450 °C. Spectral analysis reveals that the TiO2 formed was present on the carbon in anatase form. The effect of adsorption was investigated in an aqueous solution of procion blue dye in a darkroom and the photochemical reaction in aqueous suspensions of titania composite under UV illumination. The reaction was studied by monitoring the discoloration of dye via employing a UV-Visible spectrophotometeric technique as a function of irradiation time. The composite catalyst was found to be efficient in the photodegradation of the dye.
