Preparation and applications of monolithic structures containing metal–organic frameworks

Abstract

Preparation and applications of monolithic structures containing metal-organic frameworksMetal-organic frameworks are a new category of advanced porous materials with large surface areas and porosities, uniform pore sizes, tunable surface chemistry, and structural diversity. In combination with monoliths, they allow the fine tuning of desired interactions required in a variety of applications. This review article summarizes results of recent studies focused on synthetic strategies enabling incorporation of metal-organic frameworks in monolithic structures. A diverse array of applications including chromatographic separation, solid-phase microextraction, sample enrichment, heterogeneous catalysis, and enzymatic catalysis are also described.

Gel-based morphological design of zirconium metal–organic frameworks

“…Present approaches aimed at achieving this have mainly focused on structural templating, tuning synthetic conditions to control crystal growth, or on the formation of composite materials. 15–19 …”

Incorporation of metal‐organic framework amino‐modified MIL‐101 into glycidyl methacrylate monoliths for nano LC separation

“…These materials are characterized by several features such as easy preparation, good thermal and mechanical stability, Article Related Abbreviations: ACN, acetonitrile; AIBN, azobisisobutyronitrile; EDMA, ethylene dimethacrylate; GMA, glycidyl methacrylate; ICP, inductively coupled plasma; MOF, metal-organic framework; NSAID, non-steroidal anti-inflammatory drug; PAH, polyaromatic hydrocarbon uniform structured nanoscale cavities and pore topologies and high surface area. Thus, the ability of tuning the MOF properties makes them multipurpose materials with promising applications in many scientific fields such as gas storage and separation [2], catalysis [3] as well as for analytical purposes (sample preparation and chromatographic areas) [1,4,5]. However, the use of MOFs in the chromatographic field shows several disadvantages as the complicated packing of these materials for their use as stationary phases.…”

Aptamer‐modified magnetic metal‐organic framework MIL‐101 for highly efficient and selective enrichment of ochratoxin A

“…Metal‐organic frameworks (MOFs) are a relatively intriguing class of crystalline porous materials that combine metal ions with rigid organic ligands. MOFs are regarded as competitive porous materials owing to their high surface area, tunable structures, and allowable outer‐ and in‐pore surface modification and functionalization . The fascinating characteristics of MOFs also render them promising for diverse applications in analytical chemistry .…”
