Silica-supported PtSn Catalysts Obtained Through Surface Organometallic Chemistry on Metals Techniques Using a Hydrosoluble Organotin Promoter : Application to the Selective Hydrogenation of α, β-Unsaturated Aldehydes and Ketones

In this paper we propose the preparation of a PtSn bimetallic catalyst through techniques derived from Surface Organometallic Chemistry on Metals (SOMC/M) using water as solvent. The system, PtSn0.2ac, was employed in the chemoselective liquid-phase hydrogenation of acetophenone, cinnamaldehyde and...
