Multifunctional PdAg@MIL-101 for One-Pot Cascade Reactions: Combination of Host–Guest Cooperation and Bimetallic Synergy in Catalysis
Metal nanoparticles (NPs) stabilized
by metal–organic frameworks
(MOFs) are very promising for catalysis, while reports on their cooperative
catalysis for a cascade reaction have been very rare. In this work,
Pd NPs incorporated into a MOF, MIL-101, have jointly completed a
tandem reaction on the basis of MOF Lewis acidity and Pd NPs. Subsequently,
ultrafine PdAg alloy NPs (∼1.5 nm) have been encapsulated into
MIL-101. The obtained multifunctional PdAg@MIL-101 exhibits good catalytic
activity and selectivity in cascade reactions under mild conditions,
on the basis of the combination of host–guest cooperation and
bimetallic synergy, where MIL-101 affords Lewis acidity and Pd offers
hydrogenation activity while Ag greatly improves selectivity to the
target product. As far as we know, this is the first work on bimetallic
NP@MOFs as multifunctional catalysts with multiple active sites (MOF
acidity and bimetallic species) that exert respective functions and
cooperatively catalyze a one-pot cascade reaction
