Fabrication of vis-responsive anatase thin films with enhanced UV-sensitivity was attained oil in ITO pre-coated glass Substrate by applying two precursor solution involving Ti complexes of oxalic acid and EDTA. The transparent and crack-free thin films were characterized by XRD, XPS, UV-vis and FE-SEM observation. The highest sensitivity to UV light of the vis-responsive film, whose photocatalytic activity was measured by the decomposition rate of methylene blue, Was four times as compared with that formed by a sol-gel method under the same conditions. The vis-responsive films showed a characteristic absorption band at around 480 nm. (C) 2008 Elsevier B.V. All rights reserved.
