Pd‐Ni BMNPs Encapsulated in UiO‐66 as an Efficient Catalyst for the Activation of “Inert” C−O Bonds

Abstract

A catalytic system based on PdÀNi bimetallic nanoparticles (BMNPs) encapsulated in the nanocavities of UiO-66 was established for the activation of CÀO bonds in ethers. Pd 0.25 Ni 4 @UiO-66 catalyst show excellent catalytic performance in the directly methylation and arylation of ethers under a mild reaction condition. High catalytic activity of the catalyst could be ascribed to the "synergistic effect" between the two metal components and strong interaction between BMNPs and the carrier (UiO-66). BMNPs encapsulated in UiO-66 also guarantee a good reusability of the catalyst, the catalyst delivered high catalytic activity for at least four cycles. Our work highlights the great potential value of ethers as powerful alternatives for aryl halides as well as the bright future of BMNPs and MOFs in the catalysis field.

MIL‐100(Fe) Supported Pt−Co Nanoparticles as Active and Selective Heterogeneous Catalysts for Hydrogenation of 1,3‐Butadiene

“…[20] MIL-100(Fe) supported PdÀ Ni alloy NPs (PdÀ Ni@MIL-100(Fe)) displayed prominent catalytic performance for the reversible hydrogenation/hydrogenation of N-heterocycle derivatives. [21] The PdÀ Ni@MIL-100(Fe) catalyst exhibited superior catalytic stability and no significant loss in activity after being reused six times. [21] Moreover, no distinct agglomeration was visible in TEM micrographs of the recycled catalyst due to the highly porous structure and superior stability in water of the MIL-100(Fe) support.…”

Construction of 2D MOFs@reduced Graphene Oxide Nanocomposites with Enhanced Visible Light‐induced Fenton‐like Catalytic Performance by Seeded Growth Strategy

“…Over the past decades, metal‐organic frameworks (MOFs), with infinite crystalline structures formed with organic ligands and metal ions or clusters, are diffusely used in adsorption, sensor devices, drug release, environmental remediation, and catalysis fields by virtue of their structural flexibility, high specific surface area, and functional properties. In particular, MOFs with the metal nodes can be activated through absorbing light to exhibit semiconductor‐like behavior and achieve a linker‐to‐metal cluster charge transition .…”

“…[3] Among the various applications of graphene, one promising application is to construct heterogeneous graphene/semiconductor composite photocatalysts, focusing on the degradation of pollutants, [4] water splitting to H 2 , [5] CO 2 reduction, [6] and organic synthesis. [7] Over the past decades, metal-organic frameworks (MOFs), with infinite crystalline structures formed with organic ligands and metal ions or clusters, are diffusely used in adsorption, [8] sensor devices, [9] drug release, [10] environmental remediation, [11] and catalysis fields [12] by virtue of their structural flexibility, high specific surface area, and functional properties. In particular, MOFs with the metal nodes can be activated through absorbing light to exhibit semiconductor-like behavior and achieve a linker-to-metal cluster charge transition.…”

A rare earth hydride supported ruthenium catalyst for the hydrogenation ofN-heterocycles: boosting the activityviaa new hydrogen transfer path and controlling the stereoselectivity

“…Many homogenous or heterogeneous catalysts were developed for hydrogenation of N-heterocycles, which are mainly quinoline and its derivatives. 3,[14][15][16][17][18][19][20][21] For the hydrogenation of NEC, the catalysts are mainly Ru based heterogeneous catalysts. [22][23][24][25][26] Many factors such as supports and particle sizes will inuence the catalytic performance, since the hydrogenation reaction is a stepwise complex reaction ( Fig.…”
