Cu, CuSu and Cu[SnBu3](0.15) catalysts supported an SiO2 were characterized by XRD, TEM and TPR, showing a high dispersion and a strong interaction with the support. Cu was incorporated by cationic exchange while Sn was added through techniques derived from Surface Organometallic Chemistry on Metals (SOMC/M). Cu and Cu[SnBu3](0.15) catalysts appeared active and stable in the cinnamaldehyde hydrogenation reaction.
