  A subject for the invention is to provide novel titanium complexes which have a high vapor pressure and high thermal stability and serve as an excellent material for producing a titanium-containing thin film by a technique such as the CVD method or ALD method and to further provide processes for producing these complexes, titanium-containing thin films produced from the complexes, and a process for producing the thin films. The invention relates to producing a titanium complex represented by general formula (1): (wherein R 1 and R 4 each independently represent an alkyl group having 1-16 carbon atoms; R 2 and R 3 each independently represent a hydrogen atom or an alkyl group having 1-3 carbon atoms; and R 5 represents an alkyl group which has 1-16 carbon atoms and may have been substituted with one or more fluorine atoms) and to producing a titanium-containing thin film using the complex.

  该发明的一个主题是提供具有高蒸气压和高热稳定性的新型钛配合物，可作为通过CVD方法或ALD方法等技术生产含钛薄膜的优质材料，并进一步提供生产这些配合物、由这些配合物产生的含钛薄膜以及生产薄膜的工艺。该发明涉及生产由一般式（1）表示的钛配合物：（其中R1和R4各自独立地表示具有1-16个碳原子的烷基基团；R2和R3各自独立地表示氢原子或具有1-3个碳原子的烷基基团；R5表示具有1-16个碳原子的烷基基团，可能已被一个或多个氟原子取代），并使用该复合物生产含钛薄膜。
• Novel Pd/TiO2 nanocomposite prepared by modified sol–gel method for photocatalytic degradation of methylene blue dye under visible light irradiation

  TiO2 nanoparticles were prepared using the modified sol-gel method. TiO2 impregnated with Pd and/or chitosan (CS) was prepared using the impregnation method. The Pd/TiO2 composite photocatalyst was characterized by XRD, TEM, UV-Vis, PI, and BET. A methylene blue dye (MB) was used as a model pollutant to study the photocatalytic activity of TiO2 under visible light irradiation. The influence of the type and amount of catalyst as well as the initial concentration of MB was investigated. The results indicate that CS can effectively prevent the agglomeration of TiO2 nanoparticles. UV-Vis spectra demonstrated that the composite's ability to absorb visible light is greatly improved. The photocatalytic degradation of MB was found to follow first-order kinetics. Recycling experiments confirmed the relative stability of the catalyst. (C) 2013 Elsevier B.V. All rights reserved.

  The synthesis, characterization and photoactivity for the MTBE decomposition on Au/TiO2-Al2O3 and AU/TiO2 sol-gel synthesized photocatalysts are reported. The semiconductor supports TiO2, and TiO2-Al2O3 were prepared by gelling titanium and aluminum alkoxides, whereas gold nanoparticles were prepared by the deposition-precipitation method with urea. Reference Au-supported photocatalysts were also prepared using the incipient impregnation method. Nitrogen adsorption as well as XRD, UV-vis and STEM-EDAX spectroscopies was used to characterize the solids. A shift of the band gap to the visible region was observed in gold-supported solids. The E-g band of the supports was shifted to the lower energy region for gold-supported catalysts. UV-vis characterization showed a gold plasmon surface resonance band (similar to 560 nm) in catalysts showing particles >7.0 nm. It is showed that the photocatalytic decomposition of MTBE in water (500 ppm) carried out with visible-light source (; 495 nm) strongly depend of the Au particle size (6.4-25 nm). The catalysts with gold particle size <= 7.5 nm are the most active. It is proposed that in the catalyst with gold particle 7.0 nm the Au delta+ electrodeficiency is the responsible of the highest activity. Meanwhile, in catalysts with gold particles >7.0 nm the plasmon surface resonance band plays an important role in the photoactivity behavior. (C) 2007 Published by Elsevier B.V.

• Effects of the method of preparing titanium pyrophosphate catalyst on the structure and catalytic activity in oxidative dehydrogenation of n-butane
  作者：Ioan-Cezar Marcu、Ioan Sandulescu、Jean-Marc M. Millet

  Five different preparation methods have been developed to synthesize titanium pyrophosphate (TiP2O7) which are active and selective catalysts for oxidative dehydrogenation of n-butane into butene and butadiene. The crystallinity, surface area, reducibility by n-butane and acid-base properties appeared different depending upon the method used. The activity of the catalysts in the oxidative dehydrogenation of n-butane appeared to depend mostly upon their redox properties whereas the selectivity was influenced by their acidic properties. Both properties seemed to be correlated to the crystallinity of the compounds but not to their surface area. (C) 2003 Elsevier Science B.V. All rights reserved.
