Abstract

In the pursuit of advanced catalytic materials, the synergistic integration of diverse components within a single platform has emerged as a transformative strategy. This paper unveils the synthesis of Cu nanoparticles immobilized on different magnetic metal–organic frameworks [NH₂-MIL-101(Fe), MIL-101(Fe) and MIL-101(Cr)]. The main focus of the present work is to study the effect of different metal ion and ligand of the framework on the catalytic activity of Cu nanoparticles. The catalytic potential of synthesized catalysts was compared for C–N coupling and reductive degradation of organic dyes. Among the three synthesized catalysts, Cu@NH₂-MIL-101(Fe)/Fe₃O₄ demonstrated high activity attributed to the synergistic interaction between NH₂-MIL-101(Fe) and Cu as well as due to higher immobilization of catalytically active Cu nanoparticles. The catalyst offered virtues like mild reaction conditions, magnetically separable, ligand-free conditions, high product yield; and turnover number in the range of 3.68 to 5.46. Moreover, the catalyst maintains its structural integrity, chemical properties and effective magnetic response after five catalytic cycles, as demonstrated by FTIR, XRD, XPS and VSM analysis of the recycled catalyst.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
