摘　　要：Alkene hydrosilylation with homogeneous catalysts is an industrially important reaction for the preparation of organosilicon compounds such as silicone-based release coatings, surfactants, adhesives and molding products [1,2]. Moreover, alkene hydrosilylation is used for cross- linking of silicone polymers, and for coupling of silanes and siloxanes to organic polymers. For decades, noble metal based catalysts （e.g., Pt [3-7], Pd [8], Rh [9], etc. [10]） have been widely used in this dass of reactions. However, the use of precious metals catalysts with a re- latively low turn-over number （TON） represents a critical barrier to industrial applications.铂基催化剂已广泛应用于烯烃的硅氢加成反应,但贵金属铂因其稀有而价高,成为其工业化应用的障碍.为了降低成本和提高原子效率,我们采用了廉价的镍金属来代替金属铂.本文合成了一系列具有可调成分和形貌的双金属铂镍催化剂,发现其在温和条件下对烯烃的硅氢加成反应表现出优越的活性和选择性.此外,还发现八面体的铂镍纳米合金不仅能应用于具有不同的官能团烯烃,而且还有利于有机硅和硅烷偶联剂的绿色化学制备,开发出更多的新产品.
