Abstract:	本計畫屬三年期的研究計畫。目的係製造中孔洞的金屬氧化物（MgO, Na/MgO&V2O5）、奈米金屬?中孔金屬氧化物（Pd?MgO; Pd/Na/MgO; Pd?Al-Mg-O; Pd/Na/Al-Mg-O）、奈米金屬?中孔分子篩(Pd/MCM-41&Pd/MCM-48)之複合材料。利用X-射線繞射儀、物理吸附儀、電子顯微鏡、熱重分析儀、化學吸附儀、紅外線光譜儀、二氧化碳溫度程控脫附儀、氫氣溫度程控還原儀以及固態核磁共振儀來鑑定上述材料的性質，包括結構、表面積、孔洞體積與分佈、顆粒形狀與大小、鹼性、還原性以及金屬分散度。並運用於醛醇縮合、氧化與氫化反應，藉以合成工業化學品，探討反應結果與觸媒性質的關係。本計畫包括(1)觸媒材料的製備；(2)觸媒性質的鑑定；(3)觸媒的催化應用。第一年的計畫製備具大表面積與高穩定性的中孔氧化鎂、鈉/ 氧化鎂與五氧化二釩，利用合適儀器測定觸媒的各種性質。探討下列催化反應：(1)苯乙酮之縮合；(2)苯甲醛與丙酮之縮合；(3)二苯甲烷之氧化。第二年的計畫製備複合材料奈米鈀/ MCM-41 與奈米鈀/ MCM-48，利用相關儀器測定其性質，並研究下列反應：(1)環己酮之氫化；(2)乙基丙酮酸之氫化； (3)檸檬油醛之氫化。第三年的計畫製備具有雙功能之複合材料，包括奈米鈀/ 中孔氧化鎂、奈米鈀/ 鈉/ 中孔氧化鎂、以及奈米鈀/ 鎂－鋁氧化物、奈米鈀/ 鈉/鎂－鋁氧化物。利用上述儀器測定觸媒的性質。進行下列醛醇與氫化反應：(1)正丁醛； (2)正己醛；(3)正丁醛與異丁醛 The purposes of this three year research proposal include the preparation of mesoporous metal oxides (MgO, Na/MgO; V2O5) and composite materials of nanometal/mesoporous metal oxides (Pd?MgO; Pd/Na/MgO; Pd?Al-MgO; Pd/Na/Al-MgO) and nanometal/mesoporous molecular sieves (Pd/MCM-41&Pd/MCM-48). These materials are characterized with XRD, physisorption, SEM&TEM, TGA, chemisorption, FT-IR, CO2-TPD, H2-TPR and solid state NMR in order to obtain the structure, the surface area, the pore volume and pore size distribution, the particle shape and size, the basicity, the reducibility and the metal dispersion. The catalysts are utilized for reactions of aldol condensation, oxidation, and hydrogenation in order to synthesize industrial compounds. The catalytic results are correlated to catalyst properties. This proposal includes three parts: (1) the preparation of catalysts; (2) the characterization of these catalysts; (3) the catalytic application. The proposal of the first year is to prepare mesoporous MgO; Na/MgO and V2O5 with large surface area and high stability. These catalysts are characterized with various instruments to obtain their properties. The following reactions are investigated: (1) aldolization of acetophenone; (2) cross aldolization of benzaldehyde and acetone; (3) the oxidation of diphenylmethane. The proposal of the second year is to prepare composite materials of nano Pd/MCM-41 and Pd/MCM-48.The catalyst properties are characterized with appropriate techniques. The following reactions are studied: (1) the hydrogenation of cyclohexanone; (2) the hydrogenation of ethylpyruvate; (3) the hydrogenation of citral. The proposal of the third year is to prepare the dual functional composite materials such as nano Pd/mesoporous MgO; nano Pd/Na/mesoporuos MgO, nano Pd/Mg-Al mixed oxides and nano Pd/Na/Mg-Al mixed oxide. The catalyst properties are measured. The following reactions of aldolization and hydrogenation are performed: (1) n-butanal; (2) n- hexanal; (3) n-butanal and isobutanal.
