Abstract

Low temperature pure anatase Carbon Doped Titanium Dioxide (C-TiO2) is successfully synthesized by using starch as an effective, economical, and nonhazardous carbon source. The synthesized C-TiO2 has been further characterized by X-Ray Diffraction, SEM, TEM, BET, XPS and UV- DRS techniques, which reveal that the particles are crystalline with spherical morphology, high surface area and an optical band gap of 2.79 eV for CTiO2 calcined at 400 °C. Furthermore photocatalytic degradation of Rhodamine B dye was carried out using asprepared C-TiO2 under visible light irradiation. Prepared C-TiO2 calcined at 200 °C and 400 °C show higher degradation efficiency (85% and 100% in 120 min respectively) as compared to that of undoped TiO2 and commercial Degussa P-25. Result shows that the C-TiO2 containing lower carbon percentage has higher photocatalytic activity. Thus enhanced photocatalytic activity of C-TiO2, may be due to synergic effect of carbon doping and [101] facet enhanced synthesis of anatase C-TiO2.
