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 wi
th 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 t
he cinnamaldehyde hydrogenation reaction.
