Temperature-induced structural diversity of metal–organic frameworks and their applications in selective sensing of nitrobenzene and electrocatalyzing the oxygen evolution reaction

Abstract

Structure diversities can be observed in four new Co-MOFs by temperature modulated hydrothermal synthesis, which show high selectivity to nitrobenzene (NB) as well as promising oxygen evolution reaction (OER) activities.

Copper-Cluster-Based MOF as a Heterogeneous Catalyst for CO2 Chemical Fixation and Azide–Alkyne Cycloaddition

“…Generally, Cu species were employed as catalysts for AACs. − Recently, Cu species-containing/modified MOFs have been developed as heterogeneous catalysts for AACs and show promising catalytic performance (Table S2). − As we know, MOF materials usually play versatile roles such as catalysts and sensors. − Hence, MOFs with catalytic activity for different reactions can be developed as functional catalysts, offering cost-effective synthesis. As far as we know, although several MOFs have been designed and constructed, a limited number of them have been applied for catalyzing both CO 2 fixation and AACs …”

Tetraphenylpyrazine-Based Manganese Metal–Organic Framework as a Multifunctional Sensor for Cu2+, Cr3+, MnO4–, and 2,4,6-Trinitrophenol and the Construction of a Molecular Logical Gate

“…In recent years, the combination of a Lewis acid and an imidazole-functionalized ligand for MOF preparation has gained great attention because this strategy is favored for producing diverse topological structures as well as improving sensing properties, which can be ascribed to full utilization of the Lewis acid/base synergistic coordination process. − Therefore, here a multiimidazole-functionalized tetraphenylpyrazine ligand, 2,3,5,6-tetrakis­[4-[(1 H -imidazol-1-yl)­methyl]­phenyl]­pyrazine (Tipp; Scheme ), has been designed and synthesized, which was assembled together with 1,4-naphthalenedicarboxylic acid (H 2 A) and Mn 2+ ions to architect a novel three-dimensional (3D) manganese-based MOF (TippMn) in a hydrothermal atmosphere. TippMn can be developed as a multiresponsive sensor for the highly sensitive and selective detection of Cu 2+ , Cr 3+ , MnO 4 – , and 2,4,6-trinitrophenol (TNP; also known as picric acid).…”

Evolution of metal organic frameworks as electrocatalysts for water oxidation

“…In the following year, 2019, another mixed ligand MOF was reported by Han et al, prepared by employing mixed organic ligands including rigid 1,5-bi(imidazolyl)anthracene and dibenzobarrelene skeletons based dicarboxylic acid. 100 In another piece of work, a group of researchers studied the role of different anionic ligands in a bimetallic MOF derived OER catalyst, in tuning the electronic environment around the active catalytic center. 101 Ligand modification has also been reported to influence the transformation of MOFs to Co(O)OH phase during an electrocatalytic process.…”
