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 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).

AgPd nanoshells (AgPd NSs) were used as dual catalysts for hydrogen production and reduction of organic compounds in a one-pot protocol. AgPd NSs were very efficient catalysts for the reduction of several functional groups, including alkenes, alkynes, imines, nitro compounds, and azides. Excellent chemoselectivities were observed for α,β-unsaturated ketones, esters, and cinnamonitrile. Also, deuterium-labeled compounds were prepared by using D2O instead of H2O. A packed-bed reactor containing the immobilized AgPd NSs in silica (AgPd/SiO2) was designed to be used in continuous-flow conditions. An optimized flow system with AgPd NSs was able to give the desired compounds in high conversions with 30–60 min residence time (tR).

Silanols RR'R''SiOH 7 which are analog to carbinols 1 with strong odour in the region of flowery notes (lily of the valley-hyacinth-rose) were prepared via reaction steps (3) and partially unknown intermediates 6.Sila perfumes 7 are similar in intensity and spectrum of odour to 1 but a shift from lily of the valley towards hyacinth notes is generally observed.
