摘　　要：采用表面活性剂自组装、有机金属硅烷与苯基硅烷共聚法制备了有机金属Au(I)嵌于介孔材料孔壁的非均相催化剂Au(I)-PPh2-PMO(Ph).结果表明,Au(I)-PPh2-PMO(Ph)催化剂的活性位分散均匀,孔道不易堵塞,对反应物的扩散与传质影响较小,其催化活性不仅明显高于后嫁接法制得的Au(I)-PPh2-PMO(Ph)-G和均相Au(PPh3)Cl催化剂,且可以重复使用,显示出较好的应用前景.A novel periodic mesoporous Au（I） organometalsilica as an active and reusable catalyst for alkyne hydration reaction was synthesized by co-condensation of phenyl silane and organometal bridged silane.Compared with the Au-PPh2-PMO（Ph）-G prepared by the grafting method,the Au-PPh2-PMO（Ph） catalyst showed high dispersion of Au（I） active sites,straightway mesopore channels,and the reduced diffusion limit.During the hydration of terminal alkynes,the Au-PPh2-PMO（Ph） catalyst not only exhibited higher catalytic efficiency than the un-immobilized Au（PPh3）Cl catalyst but also could be used repetitively,showing good potential in industrial application.
