摘要：
F-modified C-doped TiO2 composites (CF-TiO2) were synthesized via a simple sol-gel method by using NaF as the fluorine source followed by heat treatment at 700 degrees C in nitrogen atmosphere. The as-prepared CF-TiO2 composites were characterized via transmission electron microscopy, Xray diffraction, N-2 sorption, X-ray photoelectron spectroscopy, UV-Vis diffuse reflectance spectroscopy, and photoluminescence. Carbon was doped into the anatase titania lattice, and the surface of C-doped TiO2 were modified by fluorine species. The CF-TiO2 composite showed excellent photocatalytic activity in degrading methylene blue under sunlight and simulated sunlight irradiation. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
