The use of gold, silver, platinum and palladium for preparation of bimetallic nanoshells (AgAu, AgPt, and AgPdNSs, respectively) and their use for metallo‐ and bio‐metallo catalytic applications have been described. Bimetallic nanoshells (metallo‐catalysts) were employed for silane oxidation to silanols and hydrogen (H2) production. Fast and efficient oxidation of several silanes was observed after
已经描述了金,银,铂和钯在制备双金属纳米壳(分别为AgAu,AgPt和AgPdNSs)中的用途及其在金属和生物金属催化应用中的用途。使用双金属纳米壳(金属催化剂)将硅烷氧化为硅烷醇并生产氢气(H 2)。通过使用AgPd NSs作为催化剂,丙酮作为溶剂和水作为氧化剂,在室温下仅1小时后就观察到了几种硅烷的快速有效氧化。有趣的是,由脂肪酶附着到双金属纳米壳上制备的生物金属催化剂(NSs-CALB)显示出令人鼓舞的双催化活性(酶促:酯交换反应;金属:硅烷氧化反应)。
