Reductive imination of aldehydes to the corresponding secondary imines, while attractive and promising, remains a big challenge due consecutive hydrogenation hydroammonolysis in situ formed imine. Herein, we describe strategy shape-selective catalysis for reductive biomass-derived furfural with H2NOH H2 by using Ru nanoclusters confined within regular micropores ZSM-5 (Ru@ZSM-5). The Ru@ZSM-5 features oxime-hydrogenation furfurylimine-hydrogenation their closed molecular sizes pore apertures (5.3 × 5.6 Å) ZSM-5. In contrast, imine (4.3 11.2 large size could not pass through reach active sites, thus remaining unaffected without further hydroammonolysis. shape-selectivity is confirmed catalyst-passivation hydrogen-spillover experiments. shows high activity good recyclability easily extended variety aldehydes.
