Special Issue Information

Dear Colleagues,

Metal-Organic Frameworks, also known as porous coordination polymers (PCPs) or porous coordination networks (PCNs), are among the various classes of materials that gained a global interest, predominately due to their unique textural features (e.g., significantly high surface area and porosity). Over the past decade, the number of the known frameworks/structures, theoretically or synthesized, have increased drastically, exceeding nowadays 75,000 in number (based on the Cambridge Structural Database), since a plethora of combinations of the metals, as single ions or as clusters, with the possible organic moieties for linkers exist. MOFs are recognized as promising candidates for various applications, especially due to the tunable chemistry upon functionalization or creation of defects. Although MOFs suffer from several drawbacks like the lack of stability (e.g., upon exposure to humidity, lack of reusability, and difficulties for a real-life application), a number of approaches have been devised to overcome such flaws. The formation of functionalized nanostructured MOFs, nanocomposites based on MOFs, or the dispersion of the MOF-phase on substances not only allow to bypass their drawbacks but also to enhance their functionality and performances. The utilization of the frameworks at one specific application (e.g., sensor) and then to an alternative one (such as adsorbent with or without modification) is also of a highly demanding topic to be explored for a sustainable future.

The main aim of this Special Issue, “MOF-based nanostructured materials: Synthesis and Applications” is to collect original and innovative reports (original research, communications, or review articles) presenting the very latest trends and developments on the synthesis, characterization, and applications of MOF-based nanomaterials and nanocomposites. In case of “Synthesis,” comprehensive evaluation of the materials, especially with respect to the detailed characterization of textural parameters based on comparative analysis with other materials is recommended. Further, in case of “Application.” the scope for this Special Issue is unlimited, although environmental-friendly approaches such as adsorption and catalysis are of the foremost interest.

Morphological characteristics of any nanomaterial are critical in defining its properties. In this context, a method to control morphological parameters of polyaniline (PANI) has been investigated by producing its composite with gold nanoparticles (AuNPs). Herein, we report for the first time the successful control on the physical/chemical properties of PANI composites synthesized via interfacial polymerization through functionalization of its AuNP composite component with citrate, ascorbate, glutathione (GSH), and cetyl trimethyl ammonium bromide (CTAB). A significant difference in the polymerization pattern, morphologies, and electrical properties was recognized in these composites according to the functionality of the modified AuNPs. The obtained composites of AuNPs/PANI exhibited highly diverse morphologies (e.g., nodule, hollow hemisphere, flake, and spider-web galaxy type) and electrical characteristics according to functionalization. Hence, this study is expected to offer better insight into control of the polymerization pattern of AuNP/PANI composites and their associated properties. Full article

The rapid increase of industrial activities leads to serious environmental pollution, especially, in aqueous systems and particularly with heavy metals. Cadmium, one of the most poisonous elements, is rapidly accumulated in the human body, therefore, the efficient removal of cadmium ions from wastewater is an urgent need. Coordination networks (CNs) and its subdivision metal-organic frameworks (MOFs), are structured porous composites which present various special properties. In this work two CNs were used as adsorbent materials for the removal of Cd(II) ions from aqueous solutions. By the reaction of CoSO4·7H2O and NiSO4·7H2O with N,N-bis(phosphonomethyl)glycine (Gly) in hydrothermal conditions two CNs—Co–Gly and Ni–Gly— were synthesized, respectively. Cadmium adsorption onto the studied CNs was conducted in batch mode, and the effect of pH, initial concentration, contact time, temperature and sorbent weight on the sorption process were investigated. Parametric Method 3 (PM3)semi-empirical analyses of the CNs’ structural properties were performed in order to predict the adsorption properties. For this reason, two octahedral models were calculated and computational predictions were compared with the experimental results. Both computational and experimental adsorption studies found that Ni–Gly presents higher affinity for cadmium ions. Moreover, the adsorbent materials can be readily regenerated and recycled without significant loss of cadmium uptake capacity. Full article

Metal–organic frameworks (MOFs) have significant potential for hydrogen storage. The main benefit of MOFs is their reversible and high-rate hydrogen adsorption process, whereas their biggest disadvantage is related to their operation at very low temperatures. In this study, we describe selected examples of MOF structures studied for hydrogen adsorption and different factors affecting hydrogen adsorption in MOFs. Approaches to improving hydrogen uptake are reviewed, including surface area and pore volume, in addition to the value of isosteric enthalpy of hydrogen adsorption. Nanoconfinement of metal hydrides inside MOFs is proposed as a new approach to hydrogen storage. Conclusions regarding MOFs with incorporated metal nanoparticles, which may be used as nanoscaffolds and/or H2 sorbents, are summarized as prospects for the near future. Full article
