“…Currently, this method is rarely used for the preparation MNP@MOF composite materials for catalysis. 172 Although this method allows for the synthesis of very small particles within MOFs, it requires a synthesis incorporating expensive and volatile complexes and high precision during the impregnation process to avoid MNP agglomeration on the external surface of the support.…”

More than 95% (in volume) of all today's chemical products are manufactured through catalytic processes, making research into more efficient catalytic materials a thrilling and very dynamic research field. In this regard, Metal Organic Frameworks (MOFs) offer great opportunities for the rational design of new catalytic solids, as highlighted by the unprecedented number of publications appearing over the last decade. In this review, the recent advances in the application of MOFs in heterogeneous catalysis are discussed. MOFs with intrinsic thermo-catalytic activity, as hosts for the incorporation of metal nanoparticles, as precursors for the manufacture of composite catalysts and those active in photo and electrocatalytic processes are critically reviewed. The review is wrapped up with our personal view on future research directions.

“…The gas-phase method is a method in which the gas phase is introduced into a reaction system that contains easily vaporized metal precursors as a substrate and then the gas phase is absorbed. MOF is obtained after heating and reduction of reducing gas [4]. The experimental conditions of this method are relatively simple, and it has little influence on the overall frame structure of MOF materials.…”

In recent years, MOF has been widely studied as new material. Due to its structure’s diversity, flexibility, and tunability, it is favoured by many scholars and has been used in many fields. However, due to the diversity of MOF types and the wide range of applications, there is a lack of systematic description of the application of MOF materials at present. This paper concluded several aspects of the application of MOF to close this loophole. In this paper, the preparation method including the gas-phase method, hydrothermal method, and liquid-phase epitaxy method of the MOF is introduced, then followed by the method of bringing metal nanoparticles into the prepared frame to make the doped MOF including the impregnation method and double solvent method, and then by adsorption, catalysis, and gas sensor, three aspects are briefly introduced MOF in these fields of application are introduced in these areas in different refining branch such as carbon monoxide adsorption, catalytic hydrogenation, and alkanes as nitric oxide gas sensor. Meanwhile, the challenges for this kind of material are long-term stability, heat resistance, and high cost. This paper is expected to summarize the application of MOF and hope it can bring more economic benefits and scientific value.

“…Friedrich et al 81 synthesized the iridium nanoparticles via the method of controlling the gas‐phase loading of MIL‐101 with 1.2 and 1.6 nm pore apertures in the year 2018. The author pointed out that the crucial factor for this CVD method to work is that the size of the Ir needs fit the pore size of the substrate MOF materials, stable and labile enough to be vaporized and reduced in the pores of the host materials.…”

“…This strategy will effectively prevent the aggregation of NPs and limit the growth of MNPs, and finely regulate the size and morphology of the nanoparticles. Commonly, the introduction of MNPs into MOFs is a two-step procedure: first: encapsulating the metal ions into MOFs via the following methods: solution infiltration, vapor deposition, solid grinding, and so on; second: reducing the metal ions via the different reduction methods based on the different reducing agents (hydrogen, 81 sodium borohydride, [82][83][84][85] sodium citrate, 86,87 ascorbic acid, 88 UV light, 89 ammonia borane, 90 hydrazine, 91 and heat 92 ) for metal precursors. However, it is unavoidable to depositing a few MNPs on the surface of MOFs sometimes, because of the introduction of external reducing agent and the enrichment of metal ions on the surface of the compound.…”

Metal–organic frameworks (MOFs) supported metal nanoparticles (MNPs) (MNPs@MOFs) composites, as a class of effective functional materials, have been extensively explored because of the synergetic effect of MOFs and MNPs. Lots of synthesized methods are developed to synthesize MNPs@MOFs composites. These strategies can be generally divided into four main synthesis strategies: ship‐in‐the‐bottle, bottle‐around‐the‐ship, one‐pot, and sandwich assembly approaches. In this review, the recent synthesized strategies are discussed and summarized for the design and fabrication of different MNPs@MOFs composites. Then, the catalytic applications of some MNPs@MOFs composites are presented. Lastly, the challenges and future perspectives are also pointed out in this hot research filed.
