07-P-09 - Synthesis and characterizations of mesoporous zirconia-based oxide composites J. Zhaoa; D. Wua; Y.-H. Suna*; Zh. Zhangb; H. Zhang b and D. Zhao b a Institute of Coal Chemistry, C.A.S., [email protected], P R. China b Department of Chemistry, Fudan University, Shanghai, 200433, P. R. China The thermal stability of mesoporous zirconia with tetragonal wall was greatly improved via incorporation with SiO2 and A1203. FT-IR and NMR indicated that there were chemical interactions between SiO2 (A1203) with zirconia, which strengthened tetragonal framework, thereby improving the thermal stability of crystalline mesoporous zirconia.
0 7 - P - 1 0 - Preparation and catalytic property of FeL/Y composite by a new method B. Fan, W. Fan and R. Li* Institute of Special Chemicals, Taiyuan University of Technology, Taiyuan 030024, P.R. China. E-mail: rfli~tvut, edu. cn A new method, viz. the recrystallization of MCM-41 impregnated metal complex in the synthesis system of zeolite Y, has been developed to immobilize the guest complex in zeolite host. In this way, a series of FeL/Y composites (with L=phenanthroline (phen), 8-quinolinol (Qx), salicylic acid (SA)) have been prepared. The as-prepared materials are characterized by XRD, FTIR, UV-vis, TG-DTA and ICP techniques. Furthermore, their catalytic properties in the reaction of cyclohexane oxidation were also investigated. It was shown that this method made it possible to immobilize different metal complexes, including the cationic, the anionic and the neutral. In addition, the content of metal complex can be controlled by varying its amount impregnated on MCM-41.
07-P-II - Mesoporous zirconia" an anionic surfactant inorganic composite, precursor of a tridimensional porous material G. Pacheco and J.J. Fripiat Department of Chemistry and Laboratory for Surface Studies, University of Wisconsin, Milwaukee, P.O.Box 413, Milwaukee, WI, USA. Mesoporous zirconias obtained by hydrolyzing zirconium isopropoxide at low pH (.3) in presence of alkyl straight-chain surfactant are disordered composite materials that develop high surface areas and mesoporosity. They differ essentially from mesoporous materials obtained by templating since their surface area and porosity are available in the presence of the surfactant. Another building mechanism, accounting for this difference is suggested.
