Resumen:
Silica supported bimetallic and organobimetallic PtSn catalysts were prepared by Surface Organometallic Chemistry on Metals and tested in the hydrogenation of different carbonylic compounds (butanal, butanone, cyclohexanone, benzaldehyde, crotonaldehyde and cinnamaldehyde). It was studied the influence of the Sn/Pt atomic ratio on the hydrogenation of cinnamaldehyde, having been found an optimum of approximately 0.4. The selective hydrogenation of C=O group in polyfunctional molecules can be explained on the basis of the combination of geometric (specially in organobimetallic catalysts), and electronic effects due to the presence of ionic tin.
