Selective transfer hydrogenation of nitrobenzaldehydes over an extremely active synergistic MOF@Pt@MOF catalyst

Designing and developing efficient synergistic catalytic systems has always been an exciting topic. In this work, a sandwich-type nanocomposite , UiO-66-NH 2 @Pt@PCN-222, was utilized as a synergistic catalytic system for the selective reduction of nitrobenzaldehydes to nitrobenzyl alcohols. Benefiting from the synergy of PCN-222 and Pt NPs, the catalyst can efficiently promote the formation of 10 nitrobenzyl alcohols under mild conditions within as short as 30 min. Moreover, the PCN-222 provides not only active sites but also protection for metal nanoparticles , so the catalyst remained intact activity in cycles. This work has reference significance for the construction of synergistic catalytic systems.
