Special Issue Information

Dear Colleagues,

Metal–organic frameworks (MOFs) have garnered significant attention due to their unique properties, which include a high surface area, tunable pore sizes, and versatile functionalities. MOFs have exceptional adsorption capacities, stability, and selectivity, making them ideal candidates for the storage, separation, and catalysis of gas. Moreover, their luminescent properties have opened avenues for their use in sensing and imaging technologies. Recent innovations have also explored the use of MOFs in drug delivery, showcasing their potential in biomedical applications. Overall, the multifaceted applications of MOFs are a testament to their versatility and adaptability. Continued research and development in this field promise to unlock new possibilities and enhance existing technologies across various industries. The aim of this Special Issue of Molecules is to provide an updated and integrated view on the synthesis, properties, and multifaceted applications of MOFs. Potential submissions include, but are not limited to, original scientific research articles, comprehensive reviews, and communications in the following fields: CO2 capture, CO2 reduction reactions, oxygen evolution/reduction reactions, H2 storage, H2 evolution reactions, CH4 storage, propylene/propane and O2/N2 separation, the immobilization of N2 and its conversion, water treatment, the immobilization of biomolecules, drug delivery, biomedical applications, heterogeneous catalysis, photocatalysis, fluorescent sensors, and electronic devices based on MOFs.

To achieve the “double carbon” goal, it is urgent to reform the energy system. The oxygen evolution reaction (OER) is a vital semi-reaction for many new energy-storage and conversion devices. Metal nanoparticles embedded in heteroatom-doped carbon materials prepared by the pyrolyzing of metal–organic frameworks (MOFs) have been a key route to obtain high-performance electrochemical catalysts. Herein, a nanocatalyst embedding Ni nanoparticles into S- and N-co-doped carbon nanoplate (Ni NPs@SN-CNP) has been synthesized by pyrolysis of a Ni-MOF precursor. The prepared Ni NPs@SN-CNP exhibits superior oxygen evolution performance with an overpotential of 256 mV to attain 10 mA cm−2 and a low Tafel slope value of 95 mV dec−1. Moreover, a self-assembled overall-water-splitting cell with Ni NPs@SN-CNP/NF||Pt-C/NF achieves a low potential of 1.56 V at 10 mA cm−2 and a high cycling stability for at least 10 h. The improvement in this performance is benefit from its large surface area, unique morphology, and the nanostructure of the electrocatalyst. This study presents a novel and simple approach to designing high-performance OER catalysts. Full article

Microbial fuel cell (MFC) can degrade pesticide wastewater and recovery energy simultaneously, and the activated carbon (AC) air cathode has great prospects for practical application. However, insufficient active sites and the limitation of multi-step electron transfer for oxygen reduction reaction (ORR) requires that AC should be modified by highly efficient electrocatalysts. Herein, busing the confinement effect of carbon-encapsulated metal and hollow carbon, we designed a unique ORR catalyst of Fe-Fe3O4-NC through utilizing the 2D leaf-like nanoplates of Zn-ZIF-L to load Prussian blue (PB) particles. The volatilization of low-boiled Zn and the catalysis of iron compounds led to the formation of confined walls of hollow carbon shell and carbon-encapsulated Fe/Fe3O4 particles on N-doped carbon substrate. Multivalent iron, a large surface area (368.11 m2·g−1), N doping, a heterojunction interface, and the confinement effect provided all the Fe-Fe3O4-NC-modified AC air cathodes with excellent ORR activity. The optimal samples of AC-Fe-Fe3O4-NC-3 achieved a peak power density of 1213.8 mW·m−2, demonstrating a substantial 82.8% increase over that of the bare AC. Furthermore, its efficiency in glyphosate removal reached 80.1%, surpassing the 23.2% of the bare AC. This study offers new ideas in constructing composite confined structures and the as-designed Fe-Fe3O4-NC is a promising modification candidate for the commercial adoption of AC air cathodes.
