Beschreibungen/Notizen
Pd−Ni bimetallic nanoparticles (BMNPs) encapsulated in MIL‐100(Fe) (Pd‐Ni@MIL‐100(Fe) was fabricated and employed as an efficient catalyst for the reversible dehydrogenation/hydrogenation of N‐Heterocycles derivatives in water under mild conditions. Excellent catalytic performance for both reactions endows Pd‐Ni@MIL‐100(Fe) great potential value in organic chemistry. Alloying Pd with Ni can enhance the catalytic performance due to the bimetallic synergy. Both Lewis acidity and ordered mesoporous structure of MIL‐100(Fe) are beneficial to the performance of the catalyst owing to its stabilization of BMNPs, reduction of the electron density of Pd atoms and enhancement of substrates adsorption capacity.
Bimetallics are no trick! A recyclable catalyst, Pd−Ni bimetallic nanoparticles encapsulated in MIL‐100(Fe), is fabricated and applied in acceptorless reversible dehydrogenation and hydrogenation of quinoline derivatives. Stabilization of MIL‐100(Fe) for BMNPs, absorptivity of MIL‐100(Fe) for reactants and gas together with the electronic effect between BMNPs and MIL‐100(Fe) all contribute to outstanding catalytic performance of Pd1Ni4@MIL‐100(Fe) catalyst.
