“…HKUST-1 can be introduced to alkali metals such as lithium (Li), sodium (Na), or potassium (K) to improve the gas adsorption capacity by synthesized as a modified MOF [15,16]. It is found that the HKUST-1 storage capacity is shown to be higher than the unmodified HKUST-1, when doped with modest ion amounts of lithium, sodium and potassium [17]. The Li could be the most suitable modifier due to its low atomic weight properties and the strong affinity towards the CO2 molecules.…”

The discovery of the Hong Kong University of Science and Technology-1 (HKUST-1) metal-organic framework has made a remarkable improvement in the metal-organic frameworks to achieve the goal of air polluted gas adsorption. Nowadays, HKUST-1 has become a new alternative used as an ideal platform for gas adsorption due to the open metal sites inside the structure with the large adsorption capacity and chemical tunability. The adsorption performance was related to the formation and preparation of the HKUST-1 and its effect on other fabrication parameters. The impact on the fabrications of HKUST-1, such as solvents, reactants, temperature and time, grinding process, and pressure, affected the formation of the surface area and performance of HKUST-1. Air pollution gases such as carbon dioxide (CO2), volatile organic compounds (VOCs), and methane (CH4) adsorption on HKUST-1 were studied and discussed. The structure of the HKUST-1 with the presence of the open metal sites, Lewis acid, and the benzene ring structure were the key components to act as a good adsorbate for CO2, CH4, and VOCs gas. Moreover, the incorporated post-synthesized HKUST-1, such as the added functional group, metal cations, or composite materials, could exhibit great adsorption capacities for the polluted gas instead of pristine HKUST-1.

“…Adsorbents with enhanced CO 2 capacities have also been reported, that is, metal-organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), surface functionalised silica and porous organic polymers (POPs). [73][74][75][76][77][78][79][80] Their potential for CO 2 capture has been evaluated but, particularly, carbon-based adsorbents have been extensively studied due to the promising attributes for CO 2 capture applications, such as low cost, high surface area, high amenability to pore structure modification and surface functionalisation and relative ease of regeneration. [81][82][83][84][85] Furthermore, owing to their hydrophobic nature, carbon-based adsorbents show high stability in humid conditions, though a decrease in capacity is often observed compared to the performance under dry conditions.…”

Prospects of low‐temperature solid sorbents in industrial CO₂ capture: A focus on biomass residues as precursor material

et al. 2023

Adsorption using bio-based adsorbents has been pointed out as an economical and environmentally benign technology for CO 2 gas separation and storage. A bio-based adsorbent can be fabricated from low-cost worldwide available biomass feedstock and bio-wastes from different industries (e.g., dairy manure, forestry, agriculture). As a result, it is a carbon rich material of hydrophobic nature, activated to gain high porosity development, and requires mild regeneration conditions. However, large-scale deployment of bio-based adsorption processes remains challenging. Our group has been intensively developing biomass-based adsorbents in conjunction with the design of tailored CO 2 adsorption-based cyclic processes for the envisioned application. Herein, key concepts on adsorption technology, biomass waste management, and different activation techniques for biomass-based adsorbent precursors are discussed. This review addresses the most relevant studies in the literature, from lab experimentation on a milligram scale (volumetric and gravimetric tests) to dynamic tests in bench or large-scale cyclic adsorption processes (i.e., pressure swing adsorption, temperature swing adsorption, vacuum swing adsorption). Therefore, the main target is to give a holistic view of the industrial applications where CO 2 separations with these materials are more suitable. Finally, concluding remarks and future perspectives of bio-based adsorbents in carbon capture are presented.

“…MBBs are defined as 6-connected and 5-connect nodes, respectively (Figure S2). Thus, the framework structure of MOF-1 could be regarded as an uncommon (3,5,6)-connected network with point symbol (4•6 2 )(4 5 •6 5 )(4 6 •6 8 •8). The total potential solvent accessible volumes for MOF-1 was determined to be 64.8% by summing voxels more than 1.2 Å away from the framework using PLATON software.…”

Highly Tunable MOF Luminophores Featuring Anthracene Directed Assembly and Fluorescence Regulation

et al. 2023

View full text Add to dashboard Cite

Metal−organic frameworks (MOFs) have been recognized as a potential platform for the development of tunable luminophores owing to their highly modulable structures and components. Herein, two MOF luminophores based on Cd(II) ions, 1,3,5-tri(4-pyridinyl)benzene (TPB), and 1,4-dicarboxybenzene (H 2 BDC) were constructed. The directed assembly of the metal ions and organic linkers results in [Cd 2 (BDC) 2 (TPB)(H 2 O)]•x(solvent) (MOF-1) featuring TPB-based blue fluorescence centered at 425 nm. By introducing anthracene as the structure directing agent (SDA) for assembly regulation, [Cd 2 (BDC)-(TPB) 2 (NO 3 ) 2 ]•x(solvent) (MOF-2) was obtained, which reveals anthracene feeding-dependent high tunable emission in the 517−650 nm range. Detailed components, photophysical properties, and structural characteristics investigations of MOF-2 indicate the TPB and NO 3 − interactions as the origin of its redshifted emission compared with that of MOF-1. Furthermore, the fluorescence of MOF-2 was found to be regulatable by the anthracene feeding based on the SDA-determined crystallinity of the crystalline sample. All these results provided a unique example of the structural and fluorescence regulation of MOF luminophores.
