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

Abstract

Designing and developing efficient synergistic catalytic systems has always been an exciting topic. In this work, a sandwich-type nanocomposite, UiO-66-NH2@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.
