“…Although functional groups fulfill this purpose, they occupy space, decreasing the surface area and pore volume and lower the methane deliverable capacity. One approach is to functionalize MOFs with amides [108]. UiO type MOFs are known for having highly porous structures with excellent stability, making them favorable materials for methane storage [109].…”

In this review, the evolution of paradigm shifts in CH4 adsorbent design are discussed. The criteria used as characteristic of paradigms are first reports, systematic findings, and reports of record CH4 storage or deliverable capacity. Various paradigms were used such as the systematic design of micropore affinity and pore size, functionalization, structure optimization, high throughput in silico screening, advanced material property design which includes flexibility, intrinsic heat management, mesoporosity and ultraporosity, and process condition optimization. Here, the literature is reviewed to elucidate how the approach to CH4 adsorbent design has progressed and provide strategies that could be implemented in the future.

“…In fact, once the cavities and pores are empty, there is more free space than material [16]. For this reason, conventional MOFs (which also have high surface areas but not comparable to those termed ultrahigh porous MOFs) have been more widely used in the majority of applications, such as gas storage [19], heterogeneous catalysis [20], sensors [21], drug delivery systems [22], energy storage devices [23], and in analytical chemistry applications [24][25][26][27]. Examples of different metal-organic frameworks structures with their corresponding metallic clusters and organic linkers.…”

Metal–Organic Frameworks as Key Materials for Solid-Phase Microextraction Devices—A Review

et al. 2019

View full text Add to dashboard Cite

Metal–organic frameworks (MOFs) have attracted recently considerable attention in analytical sample preparation, particularly when used as novel sorbent materials in solid-phase microextraction (SPME). MOFs are highly ordered porous crystalline structures, full of cavities. They are formed by inorganic centers (metal ion atoms or metal clusters) and organic linkers connected by covalent coordination bonds. Depending on the ratio of such precursors and the synthetic conditions, the characteristics of the resulting MOF vary significantly, thus drifting into a countless number of interesting materials with unique properties. Among astonishing features of MOFs, their high chemical and thermal stability, easy tuneability, simple synthesis, and impressive surface area (which is the highest known), are the most attractive characteristics that makes them outstanding materials in SPME. This review offers an overview on the current state of the use of MOFs in different SPME configurations, in all cases covering extraction devices coated with (or incorporating) MOFs, with particular emphases in their preparation.

“…The incorporation of this functional group in organic linkers enhances the adsorption affinity and selectivity for CO 2 due to specific binding and H-bond formation between CO 2 and amide groups. 226 Cu-TPBTM, built from the flexible C 3 -symmetric hexacarboxylate ligand with the acylamide group and Cu 2 (carboxylate) 4 paddle-wheel clusters, 112 exhibits the same topology as the prototypical rht-type MOF and other isoreticular MOFs such as the PCN-6X series. 206,218 Cu-TPBTM and the isostructural analog PCN-61 possess the same pore size, surface area, and number of Cu(II) sites, the unique difference being Figure 12.…”
