A defects-free ZIF-90/6FDA-Durene membrane based on the hydrogen bonding/covalent bonding interaction for gas separation

Bifunctional ZrO 2@ZIF-90 nanozyme with high phosphohydrolase activity for sensitive electrochemical detection of methyl parathion

“…1a and Fig. 1b, ZIF-90 crystallized with a regular three-dimensional granular morphology, and the average particle size was estimated to be ~50 nm [30] . For ZrO2@ZIF-90 (Fig.…”

Covalent connections between metal–organic frameworks and polymers including covalent organic frameworks

“…Compared with the grafting-from strategy, grafting-to is a powerful strategy with the advantage of covalently bonding the polymer to the MOF without exposing the MOF to harsh polymerization conditions, as evidenced by the successful grafting-to preparation of the covalently bonded ZIF-90-PI. 138 In this case, the grafting-from strategy failed. 62 In 2014, Mirkin's group reported pioneering results of a grafting-to strategy using heterochain polymers, which established covalent linkages between nucleic acids and MOFs via a Cu-free modified alkyne click reaction (Fig.…”

“…This composite showed a high H 2 permeability (487.0 barrer) and improved gas selectivity for H 2 /CO 2 (35.8), which was almost seven-fold higher than that of the physically mixed MOFs and polymers. 138 Liquid separation. The covalently connected MOF-polymer composites could be applied to not only gas separation but also various liquid-separation applications, including water treatment and pollutant separation.…”

Recent advances in the interfacial engineering of MOF-based mixed matrix membranes for gas separation

“…84 These characteristics of defective MOFs provide a versatile platform for improving MOF–polymer interfacial adhesion and increasing selective sorption properties. The relevant reports have demonstrated that the defective MOFs in MMMs, such as Ui-66, 19,85–88 ZIF-8, 89,90 ZIF-90, 91 and Ni-MOF, 22 show great potential for enhancing gas separation performance.…”
