Selective CO hydrogenation of cinnamaldehyde over Ir-based catalysts and its comparison with C–O hydrogenolysis of polyols

Ir–FeO x /rutile catalysts are effective for both cinnamaldehyde hydrogenation and polyol hydrogenolysis. Supplying Fe m + as adsorption site is more effective for cinnamaldehyde hydrogenation, while Fe 0 is more important in polyol hydrogenolysis.
