Special Issue Information

Dear Colleagues,

MOFs have diverse uses including gas storage, gas separation, catalysis, energy-related applications, drug delivery, environmental and biomedical applications, and more. They are particularly beneficial in separation and catalysis because of their porous structure. Moreover, MOFs have customizable features including a large surface area, persistent porosity, and multifunctional ligands.

MOFs offer advantages as heterogeneous catalysts due to their improved reactivity, flexibility, and facile tunability. When contrasting them with conventional inorganic porous materials, metal–organic frameworks (MOFs) exhibit a multifunctional nature, a highly porous structure, a consistent spatial distribution of constituents, adjustable pore sizes and topologies, and a hybrid organic–inorganic composition. Papers on the preparation and use of catalytically active MOFs are welcome in this Special Issue.

These attributes empower MOFs to perform more efficiently in energy applications than alternative porous materials. MOFs possess the capability to store energy carriers or enable rapid mass and electron transportation for energy storage and conversion, and they have been intensively investigated throughout the advancement of innovative energy technologies.

We ask for the submission of original research papers and reviews on the advances in the use of MOF-based materials for gaseous fuel storage, chemical hydrogen storage, solar and electrochemical energy storage, and conversion, in which challenges and opportunities related to advanced energy technologies are critically discussed. Further manuscripts on the use of MOFs for the separation of gaseous molecules are also welcome.

The synthesis of CoZn-MOF was accomplished via a simple hydrothermal method. The characterization of the synthesized materials was performed using X-ray diffraction (XRD), providing a thorough understanding of their structure and content. Subsequently, carbon nanotubes (CNTs) underwent three different pretreatment procedures prior to their application as an anode in a supercapacitor (SC) arrangement, with CoZn-MOF functioning as the cathode. The use of CNTs as electrode material led to an inherent improvement in conductivity and an intrinsic increase in the specific capacitance of the supercapacitor. Galvanostatic charge–discharge measurements of the three cells with different electrodes proved that the supercapacitor based on the CNT (acetic acid)//CoZn-MOF exhibited a capacity of 0.2285 F/g, a moderate energy density of 0.1944 Whkg−1 at a power density of 26.48 Wkg−1 as compared to the other two supercapacitors (CNT (nitric acid)//CoZn-MOF and CNT (unprocessed)//CoZn-MOF). This study utilized the advantages of carbon nanotubes in supercapacitor electrodes and examined the impact of CNT pretreatment. Full article
