Abstract: 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 i… Show more

“…Among them, trimetallic (Au 0.3 Pt 0.3 Pd 0.4 )/Cu(HBTC)-1 has the highest catalytic activity with a rate constant of 0.478 min −1 (nearly 2.1 times of the data from pure Au catalyst), due to strong synergistic effects among the different metals. [ 62,65,66 ] As far as we know, the catalytic efficiencies of our prepared NPs/ Cu(HBTC)-1 for this reaction are much higher than the previously reported nanocatalysts (refer to a comparative survey in Table S7, Supporting Information).…”

“…To date it has already been demonstrated that MIL-101 can act as a suitable host material for Pt [19], Pd [202 , AuNi [23], AuPd [24], AgPd [25] and PdNi [26] nanoparticles. Xu et al…”

“…used "double-solvents" method to produce MIL-101 encapsulated Pt [19], AuNi [23], and AgPd [25] nanoparticles, which were found to be active catalysts in the hydrolysis of ammoniaborane [19,23] and one-pot cascade reactions [25]. Kempe and co-workers achieved the synthesis of bimetallic PdNi nanoparticles within the cavities of MIL-101 by gas phase infiltration of [(C 5 H 5 )Pd(C 3 H 5 )] and [(C 5 H 5 ) 2 Ni] followed by their dihydrogen reduction.…”

“…22 A recent report of encapsulated Pd@NH 2 -UiO-66 has shown activity towards an oxidationacetalisation tandem reaction that converts benzyl alcohol into 2-phenyl-1,3-dioxolane, although TONs remain modest after 22 hours of reaction, 23 and a similar PdAg@MIL-101 also showed activity toward a hydrogenation-reductive amination process to generate secondary arylamines from benzaldehyde and nitrobenzene. 24 This does, however, highlight the scope and potential of applying NP/MOF materials in consecutive processes, especially with the breadth of existing single-step catalytic applications of the separate NP and MOF entities. Herein, we present the facile preparation of highly active and selective nanoscale Au/NH 2 -UiO-66 catalysts for one-pot, tandem reactions; firstly involving selective oxidation of cinnamyl alcohol, a primary alcohol, and the subsequent Knoevenagel condensation of the resulting aldehyde product with malononitrile.…”
