Bimetallic Ag–Ru/γ‐Al 2 O 3 nanoparticles for selective hydrogenation of cinnamaldehyde to hydrocinnamaldehyde

This work reports an efficient co-catalyst of AgRu nanoparticles supported on γ-Al2O3 for highly selective hydrogenation of the C=C bond of cinnamaldehyde (CAL) at 443 K, uncovering a catalytic route for selective hydrocinnamaldehyde production from the CAL. This kind of chemo-selectivity of AgRu/γ-Al2O3 catalyst seems unique since any competitive hydrogenation at the conjugated C=O bond was significant.
