Special Issue Information

Dear Colleagues,

Metal–organic frameworks (MOFs) are emerging materials for various applications in energy conversion and storage technologies, such as electrolyzers, batteries, fuel cells and environmental remedial technologies, including sensing, wastewater treatment, biodegradation, etc. MOFs and the derived nanomaterials have a unique morphology, physical and chemical properties, which endow them with broader application prospects. MOF-derived carbon nanomaterials are widely used in electro and photocatalysis (oxygen electrocatalysis, CO2 reduction reaction, water-splitting, etc.). Therefore, this Special Issue will focus on the versatile applications of MOFs and their derivatives in electro-photocatalysis. This Special Issue will cover the following related topics: i) MOF-based materials for electrocatalysis, including ORR, OER, HER, CO2RR and so on; ii) MOF derivatives for photocatalysis, including water splitting, CO2RR, energy conversion, and environmental remedies such as pollutant degradation, the disinfection of microbes, and fuel production; iii) synthesis and characterization of MOFs using state-of-the-art strategies to expand their application prospects in electro-photocatalysis; iv) practical application and analysis of different features, such as conductivity, catalytic activity and stability, and their degradation mechanism and mitigation strategies; v) scaleup synthesis of MOFs toward commercial applications.

Lead-based electro-ceramic compositions are excellent energy storage materials used for high-energy storage density applications in dielectric ceramic capacitors. However, these materials have lead contents in their compositions, making them toxic, with a negative impact on human health and the environment. For this reason, we synthesized a lead-free bismuth-based electro-ceramic perovskite, 0.80(0.92Bi1/5Na1/5TiO3-0.08BaTiO3)-0.20(Na0.73Bi0.09NbO3−xTa2O5), abbreviated (BNT-BT-NBN1−xTx), from mixed oxides with doping of tantalum (Ta) at different concentrations, using a conventional solid-state reaction method. The effects of Ta doping on the phase evolution, microstructure development, and energy storage applications were investigated. Detailed powder X-ray diffraction analysis revealed a pure perovskite phase with Ta doping at ≤0.05. Furthermore, it was observed that excessive addition of Ta has been resulted in secondary phase generation. Scanning electron microscopy validated the development of dense microstructures with a reduced grain size for the Ta concentration of ≤0.01. Electrochemical analysis revealed a maximum polarization (Pm) of ~22 µC/cm2 and a recoverable energy density of 1.57 J/cm3 with 80% efficiency for Ta doping at 0.05 with an applied field of 175 kV/cm. These results demonstrate the development of enhanced ferroelectric characteristics in an as-synthesized electro-ceramic perovskite for high-energy storage density applications in electro-ceramic capacitors.

Two-dimensional (2D) metal-organic frameworks (MOFs) are fascinating photocatalytic materials because of their unique physical and catalytic properties. Herein, we report a new (E)-4-(3-carboxyacrylamido) benzoic acid [ABA–MA] ligand synthesized under facile conditions. This ABA–MA ligand is further utilized to synthesize a copper-based 2D MOF via the solvothermal process. The resulting 2D MOF is characterized for morphology and electronic structural analysis using advanced techniques, such as proton nuclear magnetic resonance, Fourier-transform infrared spectroscopy, ultraviolet-visible spectroscopy, and scanning electron microscopy. Furthermore, 2D MOF is employed as a photocatalyst for degrading organic dyes, demonstrating the degradation/reduction of methylene blue (MeBl) dye with excellent catalytic/photodegradation activity in the absence of any photosensitizer or cocatalyst. The apparent rate constant (kap) values for the catalytic degradation/reduction of MeBl on the Cu(II)–[ABA-MA] MOF are reported to be 0.0093 min−1, 0.0187 min−1, and 0.2539 min−1 under different conditions of sunlight and NaBH4. The kinetics and stability evaluations reveal the noteworthy photocatalytic potential of the Cu(II)–[ABA–MA] MOF for wastewater treatment. This work offers new insights into the fabrication of new MOFs for highly versatile photocatalytic applications. Full article
