摘　　要：硅氢加成反应中,固载型催化剂可以弥补均相和多相催化剂的不足,可提高硅氢加成反应催化剂活性和区域选择性。系统阐述固载型催化剂的反应机理、制备方法、活性组分、固载体、配位体、催化剂表征以及区域选择性影响因素。今后可能的研究方向是,尝试更多的催化剂固载化技术,探索和制备出更加低廉的非贵金属催化剂,有针对性地研究加成反应区域选择性,以及进一步拓展硅氢加成在有机合成中的应用领域。The supported catalysts are used to improve the activity and selectivity for the hydrosilylation reaction and offset some disadvantages, comparing to the homogeneous and heterogeneous catalysts. This review presented the mechanism and fabrication method of the catalysts, active ingredient, supporter, ligand, characterization, factors impacting on the selectivity. In future, possible researching directions include attempting to more supported technologies, fabricating inexpensive metal catalysts,studying zone selectivity for hydrosilylation, and extending application domains of supported catalyst and hydrosilylation in organic synthesis field.
