“…Various porous materials, such as activated carbons, [8] silica [9] and metal‐organic frameworks (MOFs), [3, 10–19] have been studied for the adsorptive separation of C 2 H 2 /CO 2 . MOFs attracted particular attention because of their abundant structural diversity and design flexibility [20–24] . Zeolites, as conventional sorbent materials, [25, 26] are potentially superior to MOFs for gas separations at an industrial scale owing to their high hydrothermal stability, recyclability and low production cost.…”

Efficient Separation of Acetylene and Carbon Dioxide in a Decorated Zeolite

The almost identical molecular sizes and volatilities of acetylene and carbon dioxide make their separation extremely challenging in industry. Reported here is the efficient separation of acetylene and carbon dioxide (v/v=2/1, which is relevant to that in the industrial cracking stream) in faujasite zeolites decorated with atomically‐dispersed copper(II) sites under ambient conditions. In situ neutron powder diffraction and inelastic neutron scattering confirm that the confined copper(II) site displays chemoselective yet reversible binding to acetylene, whereas adsorbed carbon dioxide molecules are stabilized by weak host–guest supramolecular interactions with the framework oxygen centers, thus resulting in the efficient separation of these two gases under flow conditions. A designed adsorption‐purging‐desorption system based upon Cu@FAU is established for the recovery of high purity acetylene (98–99 %) from the mixture of acetylene and carbon dioxide, offering an unprecedented separation factor of 22.2 with an effective dynamic uptake of acetylene of 1.51 mmol g−1 at 298 K.

“…catalysis or information storage or selective host/guest chemistry. 11,68 An intriguing recent development along similar lines is the concept of using correlated disordered states as intermediates in materials synthesis to target low-dimensional phases. 17 But we note in conclusion the possible additional importance of different types of correlated disorder in MOFs to those outlined here-involving e.g.…”

“…It is now well established that many MOF architectures are tolerant to the incorporation of multiple different metals and/or linkers within the one material. 7,11,52,53 In such cases an obvious consideration is whether composition is homogeneously distributed or varies in some nonstatistical way-e.g. domain formation or core-shell architectures.…”

“…the amino-acids of their protein backbone-the vision with compositionally complex MOFs has always been one of controlling heterogeneity to optimise a particular chemical or physical property. 11 A simple but effective example is the recent demonstration of correlationdependent photocatalysis in a mixed-linker UiO-68 derivative. 66 But this vision is not unique to the MOF field: indeed, conventional solid-state chemistry has long exploited the use of solid solutions and inhomogeneity in this general way.…”

“…7 Having long focused on the elegant control possible over crystalline network structures, 8,9 the field is now increasingly exploiting the presence and nature of disorder in MOFs as an important design tool with which to tune their physical and chemical properties. 10,11 Disorder is sometimes random; more often it is correlated. 12 A vacancy at one linker site in an otherwise crystalline MOF, for example, may affect the likelihood for neighbouring linkers also to be vacant.…”

Metal‐organic frameworks (MOFs), an emerging class of porous crystalline material, are identified as a promising candidate for tackling the most formidable global challenges due to their unique and intriguing properties including well‐defined porous crystal structure, large specific surface area, and vast tunable chemical and physical property. Air pollution resulting from various toxic gases, volatile organic compounds, and fine particulate matters has posed a big threat to human health and ecological sustainability. In recent years, various MOFs are studied and shown great potential as active materials for air pollution control in both pollutant detection and air quality remediation. In this review, the most recent research progress for MOFs‐based materials for air pollution control is summarized. The discussion is categorized based on the different approaches for air quality control with a focus on the performance correlations to the structure and functionality of MOFs. In addition, the technical merits and downsides of each approach are discussed based on their application scenarios. Finally, the remaining challenges and future research directions in this field are proposed.
