中文摘要：

以2-（二苯基膦）乙基三乙氧基硅烷和正硅酸乙酯为混合硅源，采用延时共缩聚法经表面活性剂F127自组装合成了二苯基膦（PPh2）修饰的SBA-16纳米介孔分子筛（PPh2-SBA-16），通过PPh2配体络合Ru（Ⅱ）化合物制备出固载化的Ru（Ⅱ）非均相催化剂（Ru-PPh2-SBA-16），样品仍然保持了SBA-16的规整孔道结构．以水相中高烯丙醇异构化反应为探针，考察了所制备催化剂的催化性能，发现其对目标产物具有高选择性，虽然其催化活性略低于对应的均相Ru（Ⅱ）催化剂，但该催化剂易与产物分离，且重复使用三次后催化效率基本不变，活性相与载体结合牢固，不存在明显的脱落和流失，因此更适合于工业化应用．

英文摘要：

Based on the serf-assembly of F127, a new SBA-16-1ike mesoporous silica modified with diphenylphosphine group （ PPh2-SBA-16 ） was synthesized by extend co-condensation with tetraethoxysilane （TEOS） and 2-（diphenylphosphino） ethyltriethoxysilane （DPPTS） as the mixed silicon source. The PPh2-SBA-16 was used as a support to immobilize the Ru （ Ⅱ ） ions through strong coordination between PPh2-group and Ru（ Ⅱ ）, denoted as Ru-PPh2-SBA-16. The characterizations demonstrate that the Ru-PPh2-SBA-16 still remained ordered mesoporous structure. During the isomerization of homoallylic alcohols carried in water as a environmentally friendly medium, the as-prepared Ru-PPh2-SBA-16 catalyst exhibited an excellent selectivity, almost the same as the corresponding homogeneous catalyst [ RuCl2 （ PPh3 ） 3 ]. Although its activity was slightly lower than that of RuCl2 （PPh3）3, the Ru-PPh2-SBA-16 could be considered more suitable for industrial application based on the following benefits ： （ 1 ） The catalyst could be easily separated from the reaction products. （2） The catalyst could be used repetitively at least for 3 times without significant activity decrease. （3） The Ru（ Ⅱ ） was strongly immobilized on the support which could effectively inhibit the leaching of active sites and protect the environmental pollution from heavy metals.
