The use of methanol as an abundant and low-toxic hydrogen source under mild and clean conditions is promising for the development of safe and sustainable reduction processes, but remains a daunting challenge. This work presents a recyclable ZnO-supported Ir catalyst for the additive-free transfer hydrogenation of aldehydes and ketones using methanol as the hydrogen source at 110°C, delivering alcs. in up to 98% yield. Mechanistic studies disclose that methanol was first dehydrogenated to formaldehyde and then fully decomposed into an active hydrogen species for hydrogenation. The superior performance is related to the high ratio of pos. charged IrOx species and their ultrafine dispersion over ZnO. And the delicate cooperation of IrOx and ZnO enhances the catalytic activities for the selective scission of O-H and less reactive C-H bonds in methanol, maintaining a good balance between methanol decomposition and C=O hydrogenation in this green transfer hydrogenation.
