Selective Oxidation In their contribution on page 118 ff., Gómez, Serp, and co-workers describe efficient catalysts for the selective hydrogenation of cinnamaldehyde to cinnamyl alcohol, the chemical responsible for the hyacinth's scent. Bimetallic platinum/ruthenium nanoparticles stabilized by simple ligands were prepared in both THF and supercritical carbon dioxide, giving more dispersed particles than those prepared in the organic solvent. Their confinement in multi-walled carbon nanotubes could be achieved thanks to the appropriate functionalization of the support by amide groups containing a long alkyl chain. The higher selectivity observed for the confined catalysts in relation to the non-confined ones, can be attributed to the higher concentration of reactants inside the multi-walled carbon nanotubes.
