“…The conversion of Cu(OH) 2 into HKUST-1 could be carried out at room temperature and was suitable for large scale production. [24][25][26][27][28] Zinc oxide is an n-type semiconductor with many potential applications and ZnO nanostructures have the richest morphologies including various nanorods, nanopillars, nanowires, nanodonats, nanodrums, nanopropellers, nanonails, and nanobridges. 19 Falcaro's group used ZnO particles as heterogeneous nucleation agents for seeding, growing, and precisely positioning Zn-based metal organic frameworks including MOF-5, IRMOF-3, IRMOF-8 and IRMOF-10.…”

MOF-46 and a novel core-shell heterostructure containing ZnO@MOF-46 rods have been successfully synthesized via a simple, versatile and economic method. The products have been characterized by X-ray diffraction (XRD), FTIR spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX). Time and solvent effects on the growth process of ZnO@MOF-46 were investigated. Luminescent properties of the activated sample showed distinct solvent-dependent photoluminescence emissions. The product also demonstrated unique sensing properties in detection of aromatic compounds via a fluorescence quenching and enhancing mechanism. Aromatic compounds with electron-withdrawing substituents such as nitro act as fluorescence quenchers for ZnO@MOF-46 and aromatic compounds with electron-donating substituents such as CH3 were found to enhance the ZnO@MOF-46 fluorescence. The ZnO@MOF-46 showed excellent photodegradation of methylene blue. The degradation rates in presence of various scavengers including benzoquinone, isopropyl alcohol and ammonium oxalate (O2 •-, OH • and h + scavengers, respectively) were studied and the results showed all of species (O2 •-, OH • and h + ) contribute to degradation but the OH • is the main active species and plays a major role in this system and hence photocatalyst degradation was supposed to have a radical mechanism. Band structure parameters of ZnO@MOF-46 were determined using cyclic voltammetry and DRUV/VIS spectroscopy and the mechanism of photodegradation was then discussed.

“…94 Furthermore, MOFs have also been exploited for the encapsulation of active species, 95 which can be as varied as chromophores, [96][97][98] drugs, 99 CO releasing molecules, 100 catalysts, [101][102][103][104][105] or nanoparticles. [106][107][108] Using this hybrid approach two-network solids can be prepared through the self-assembly of different molecular fragments (organic, inorganic, or organometallic) used as starting building blocks, or using a post-synthetic method in which a molecular guest is inserted into a pre-formed extended network acting as the host lattice (Fig. 28).…”

In this review, we show the different approaches developed so far to prepare metal-organic frameworks (MOFs) presenting electronic functionalities, with particular attention to magnetic properties. We will cover the chemical design of frameworks necessary for the incorporation of different magnetic phenomena, as well as the encapsulation of functional species in their pores leading to hybrid multifunctional MOFs combining an extended lattice with a molecular lattice.

“…The incomplete degradation of such toxic chemicals and dyes by aerobic methods cause significant disturbance in aquatic life and hence pose a dangerous threat to aquatic animals [12][13][14][15][16][17][18]. Environmental scientists have adopted various approaches such as filtration, coagulation, flocculation, degradation, adsorption, and so on to overcome such dangerous threat [19][20][21].…”
