Facile synthesis of hierarchical micro-mesoporous HKUST-1 by a mixed-linker defect strategy for enhanced adsorptive removal of benzothiophene from fuel

Computational Investigations of Metal–Organic Frameworks as Sorbents for BTEX Removal

“…In fact, experimental work by Guo et. al demonstrated increased performance of HKUST-1 for capture of benzothiophene upon introduction of such defects, which would be explained in part by the mechanism proposed here . Additionally, recent work has demonstrated increasing the dimensionality of organic linkers to modify the flexibility and thereby the pore size available to guest BTEX molecules …”

Template-Free Synthesis and Multifunctional Application of Foam HKUST-1

“…HKUST-1K (HKUST = Hong Kong University of Science and Technology), also known as MOF-199, is one of the handful of MOFs with real-world prospects with the chemical formula 3D-[Cu 3 (BTC) 2 (H 2 O) 3 ] (Figure S1 in the Supporting Information). , It is a prototypical microporous MOF with a pore size of about 9 × 9 Å. HKUST-1 has many merits such as simple synthesis, high porosity and specific surface area (>1000 m 2 g –1 ), stable and reliable performance, and excellent water stability. , Hence, it promises applications in, e.g., gas storage/separation, – catalysis, drug delivery, sensors, and so on. In fact, the preparation and applications of the HP-HKUST-1 have been of interest to researchers in recent years. , Nevertheless, the approaches they employed were mainly etching, modulating, or mixed-linker strategies, and the mesopores/macropores were the defective ones on the micron-sized crystals of HKUST-1 to achieve the formation of hierarchical pores. – So, the obtained crystals of HP-HKUST-1 produced by these processes are actually partly corrupted, and each grain is still isolated, which indicates that the hierarchical pores are not fully connected.…”

A novel strontium-based MOF: synthesis, characterization, and promising application in removal of 152+154Eu from active waste

“…15 Commonly, they have low density, large pore size; high thermal and chemical stability, insoluble in aqueous solutions, and extended surface area in a range from 10 3 to 10 4 m 2 g −1 , which enhances their suitability for removal and separation of radionuclides and toxic inorganic pollutants. MOFs have also numerous applications not only for radionuclides removal 16 but also for gas storage and separation, 17 toxic chemicals removal, 18 catalysis, 19 fuel desulfurization, 20,21 sensors/biosensors, 22–28 moisture control, 29 proton conductivity, 30 and drug delivery. 31 Furthermore, MOFs were applied for the adsorption of some radionuclides.…”
