A Family of Metal‐Organic Frameworks Exhibiting Size‐Selective Catalysis with Encapsulated Noble‐Metal Nanoparticles

Abstract

The encapsulation of noble-metal nanoparticles (NPs) in metal-organic frameworks (MOFs) with carboxylic acid ligands, the most extensive branch of the MOF family, gives NP/MOF composites that exhibit excellent shape-selective catalytic performance in olefin hydrogenation, aqueous reaction in the reduction of 4-nitrophenol, and faster molecular diffusion in CO oxidation. The strategy of using functionalized cavities of MOFs as hosts for different metal NPs looks promising for the development of high-performance heterogeneous catalysts.

Ag2CO3/UiO-66(Zr) composite with enhanced visible-light promoted photocatalytic activity for dye degradation

“…UiO-66 not only possesses the excellent properties as other MOFs, but also exhibits higher thermostability and chemical stability, thus it has been extensively researched in the fields of catalysis, hydrogen generation, gas storage, drug delivery, etc. [47][48][49][50][51]. Moreover, UiO-66 also demonstrates excellent structural stability in water [52,53], and such stability can even be preserved after modification of active functional groups or introduction of missing-linker defects [54,55].…”

“…[13] They have been synthesized using a variety of organic ligands including ditopic, tritopic, tetratopic, hexatopic, octatopic, mixed, desymmetrized, metallo, and N-heterocyclic linkers. [14] MOFs have typically been used for gas adsorption and separation, [15] catalysis, [16] luminescence, [17] sensing, [18] proton conduction [19] and their properties could potentially be useful for biomedical applications. [20] Although potentially interesting for biomedical applications, MOFs tend to be not stable in physiological protein-containing solution.…”

One step hydrothermal synthesis of transition metal based coordination polymers along with magnetic and electrical conductive Ag and Au nanospheres and rods

“…Another approach involves synthesis of MOFs around the pre-stabilized nanoparticles by utilizing surface capping agents to prevent agglomeration [8,9]. Complete removal of these surface stabilizing agents are very difficult because of their negative effect on catalytic performance of NPs used as heterogeneous catalysts for catalysis [10].…”
