“…The MOF-based catalysts have recently been shown to bring about competitive selectivity and efficiency, even with earth-abundant metal-based catalysts. Zhang’s group reported the MOF catalyst Cu-BTC@Fe 3 O 4 (BTC = 1,3,5-benzenetricarboxylate) for nitroarene reduction by NaBH 4 to anilines in aqueous medium under mild conditions and catalyst separation with an external permanent magnet allowing six-time recycling . Gascon et al synthesized Co@mesoNC with dispersed Co-Nx sites by carbonization of a bimetallic Zn/Co ZIF precursor. , Co@mesoNC shows good catalytic performance for the hydrogenation of nitrobenzene and excellent chemoselectivity in hydrogenation of substituted nitroarenes; it selectively reduced the nitro group without affecting double bonds and other substituents such as halogen, −OCH 3 , and −COCH 3 .…”

Metal–organic framework (MOF) nanoparticles, also called porous coordination polymers, are a major part of nanomaterials science, and their role in catalysis is becoming central. The extraordinary variability and richness of their structures afford engineering synergies between the metal nodes, functional linkers, encapsulated substrates, or nanoparticles for multiple and selective heterogeneous interactions and activations in these MOF-based nanocatalysts. Pyrolysis of MOF-nanoparticle composites forms highly porous N- or P-doped graphitized MOF-derived nanomaterials that are increasingly used as efficient catalysts especially in electro- and photocatalysis. This review first briefly summarizes this background of MOF nanoparticle catalysis and then comprehensively reviews the fast-growing literature reported during the last years. The major parts are catalysis of organic and molecular reactions, electrocatalysis, photocatalysis, and views of prospects. Major challenges of our society are addressed using these well-defined heterogeneous catalysts in the fields of synthesis, energy, and environment. In spite of the many achievements, enormous progress is still necessary to improve our understanding of the processes involved beyond the proof-of-concept, particularly for selective methane oxidation, hydrogen production, water splitting, CO2 reduction to methanol, nitrogen fixation, and water depollution.

“…Anilines can be obtained through the reduction of nitroarene compounds which is possible by using a catalyst and a reductant such as NaBH 4 which is cheap and accessible but have some problems such as long reaction time and difficult recovery and reusability. Magnetic Cu‐BTC@Fe 3 O 4 catalyst was developed in 2017 by Yeng and research team which could reduce nitroarene compounds under mild reaction conditions in aqueous medium using sodium borohydride as the reducing agent in a recoverable manner . The reusability of the Cu‐BTC@Fe 3 O 4 catalyst was tested after facile recovery by applying an external magnetic field, and it showed only a minor reduction in its activity after six times.…”

In this review, we gather a great deal of information about magnetic nanocomposites, which are made from the combination of Fe 3 O 4 magnetic nanoparticles (MNPs) and metal-organic frameworks (MOFs). Due to the high saturation magnetization, biocompatibility, low toxicity, stability, and costeffectiveness, MNPs have attracted a lot of interest in recent years. Furthermore, MOFs, which are porous materials, formed by the connection between organic linkers and metal ions. The combination of MNPs and MOFs results in the formation of magnetic framework composites (MFCs). The information about the MFCs is classified according to their applications and we

“…The second finding concerns the rarely observed intermetallic nanodots of Ag 3 Sb generated in the process of themocylizing the alkynyl units of the MOF host. The resultant composite consists of the Ag 3 Sb nanodeposit and the partially graphitized scaffold, and exhibits efficient cyclable/heterogeneous catalytic activities for making azo compounds from cheap nitro precursors, with yields being comparable to that of Pd-/Au-catalytic systems. , It is worth noting that much efforts have been devoted to MOFs/MOFs derived catalysts for making aniline products from nitroarenes, − but studies on modulating their catalytic activity for azo synthesis have been rare. Besides helping to solve the challenging structure of a porous framework, the AgSbF 6 guests in the present case take on some importance in the broader context of metalating MOFs for functionalization and application.…”

The infusion of metal guests into (i.e., metalating) the porous medium of metal−organic frameworks (MOFs) is a topical approach to wide-ranging functionalization purposes. We report the notable interactions of AgSbF 6 guests with the designer MOF host ZrL1 [Zr 6 O 4 (OH) 7 (L1) 4.5 (H 2 O) 4 ]. (1) The heavyatom guests of AgSbF 6 induce order in the MOF host to allow the movable alkyne side arm to be fully located by X-ray diffraction, but they themselves curiously remain highly disordered and absent in the strucutral model. The enhanced order of the framework can be generally ascribed to interaction of the silver guests with the host alkyne and thioether functions, while the invisible heavy-atom guest represents a new phenomenon in the metalation of open framework materials. (2) The AgSbF 6 guests also participate in the thermocyclization of the vicinal alkyne units of the L1 linker (at 450 °C) and form the rare nanoparticle of Ag 3 Sb supported on the concomitantly formed nanographene network. The resulted composite exhibits high electrical conductivity (1.0 S/cm) as well as useful, mitigated catalytic activity for selectively converting nitroarenes into the industrially important azo compounds, i.e., without overshooting to form the amine side products. The heterogeneous/cyclable catalysis entails only the cheap reducing reagents of NaBH 4 , ethanol, and water, with yields being generally close to 90%.Article pubs.acs.org/IC
