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 (H 2 ) production. Fast and efficient oxidation of several silanes was observed after only 1 h at room temperature, by employing AgPd NSs as catalyst, acetone as solvent, and water as oxidant. Interestingly, bio‐metallo‐catalysts (NSs‐CALB) prepared from lipase attachment to the bimetallic nanoshells, displayed promising bi‐catalytic activities (enzymatic: transesterification; metallic: silane oxidation).
