Constructing strategies for hierarchically porous MOFs with different pore sizes and applications in adsorption and catalysis

Abstract

Since metal-organic frameworks, a versatile class of crystalline organic-inorganic hybrid materials featuring well-aligned intrinsic porosity, have come of age, the research focus has shifted from structural considerations toward the many...

Heterogeneous Photocatalysts for Light‐Mediated Reversible Deactivation Radical Polymerization

“…Using these approaches, MOFs have been functionalized with carbazoles, [259] xanthene dyes, [260] pyrene, [261] and other photocatalytic groups [258,259] and have shown efficiency for the neutralization of hazardous gases, [261] hydrogen generation, [262] as well as in organic transformations [263,264] . MOFs are inherently porous with tunable pore sizes – a key property that allows for good diffusion of substrates to the catalyst sites [265–267] . Simultaneously, plentiful opportunities arise to improve selectivity through modulation of the pore sizes [268] .…”

“…Some reports of polymers [266] or surfactants [288] clogging MOF pores highlight that extra consideration is required for the design of MOFs for polymerization. As mentioned in the work by Zhang et al., catalyst rejuvenation via refluxing may recover catalyst performance, suggesting that catalyst clogging may be a greater concern than MOF photodegradation [281] .…”

“…[263,264] MOFs are inherently porous with tunable pore sizes -a key property that allows for good diffusion of substrates to the catalyst sites. [265][266][267] Simultaneously, plentiful opportunities arise to improve selectivity through modulation of the pore sizes. [268] Highlighting the importance of this porosity, breaking MOFs into smaller pieces to increase surface area has shown to not improve photocatalytic performance in some cases.…”

Recent advances in separation membranes based on porous organic molecular materials

“…1). Because of the high porosity, uniform and tunable pore size, well-defined pore structure, and adjustable surface properties of MOF and COF membranes, [12][13][14][15] they are still dominant membrane materials. However, the processability of these framework materials, in addition to their relatively low thermal, chemical, and moisture stabilities, limited their industrial valorization.…”

Organophosphonic acid and cerium functionalized antimonotungstate with electrochemical promise in biosensing bacterial dissimilatory sulfite reductase gene sequence

“…Organically functionalized cluster-based materials (OFCMs) have attracted enormous interest as they can generally demonstrate various structures as well as serviceable functionalities. 1,2 To further facilitate OFCMs moving forward, tremendous efforts have been made to construct unique structures and explore their performances, which endow them with great potential in various fields such as materials science, 3 energy conversion and storage, 4 biomedicine, 5,6 and catalysis, 7,8 among others. In recent years, organic-inorganic hybrid polyoxometalates (POMs) have become a burgeoning research theme in OFCMs.…”
