摘要：A visible light TiO2 photocatalyst was prepared by a surface chemical modification process with toluene 2,4-diisocyanate (TDI). Because of the LMCT excition of the surface complex, the as-prepared TiO2-TDI has an obvious absorption in visible region. TiO2-TDI photocatalyst presented a satisfactory photostability and a high photocatalytic performance for the degradation of organics. The turnover number of the photocatalyst for 2,4-dichlorophenol photodegradation reached 15.43 after five times recycled under visible light irradiation. (C) 2009 Elsevier B. V. All rights reserved.
