“…Metal–organic frameworks (MOFs) were notorious as polymers with porous coordination. − MOFs have porous structures facilitated by the coordinated bonding of metal clusters or ions with bridging ligands or organic linkers as defined by Yaghi et al − ,− Over the last 50 decades, porous materials, including coordinated polymers, zeolites, and MOFs, have been attracting significant interest. − The fascinating aspect was their porosity that enables guest molecules to spread out into the bulk structure. − A wide range of different organic and inorganic components could be utilized for the fabrication of MOFs, and their permeability has allowed the appropriate design and integration of materials with new topologies and extraordinary properties. , Usually, they are crystalline compounds made from organic multidentate ligands and metal ions or clusters. Covalent and/or coordinate bonds link up the two components together to form extended infinite three-dimensional (3D) network structures. , MOFs can be synthesized using solvothermal, hydrothermal, ultrasonic, mechanochemical, and electrochemical methods.…”

Metal−organic frameworks (MOFs) are attractive materials to be used as ionophores because of the array of nurturing features for instance a significant surface area, a porous structure, and also electrocatalytic activity. Aluminum is an important metal regarding its many applications such as in industry, biology, medicine, and so forth, so its estimation in very low levels is a challenging mission. Herein, a carbon paste electrode has been developed based on a novel prepared Cu-MOF with a nano-Schiff base linker. The prepared ionophore was characterized using many analytical and spectroscopic methods. The X-ray diffraction data suggested that the newly synthesized Cu-MOF has a mesoporous structure. For Al(III) determination in different real water and pharmaceutical samples, the established electrode has been successfully used with high precision (RSD% = 0.82−1.98) and accuracy (recovery % = 98.0−101.2) and showed good agreement with the atomic absorption spectroscopy results. The sensor under study exhibited Nernstian behavior toward the Al(III) ion (19.89 ± 0.63 mV decade −1 ) wrapping a large linear range of 1.0 × 10 −7 to 1.0 × 10 −1 mol L −1 with a low detection limit of 3.31 × 10 −8 mol L −1 . The working pH was 2.3−6.5 and the response time was 6 s. The fabricated sensor was highly selective for Al(III) ions. The response mechanism and surface reaction have been studied via scanning electron microscopy combined with energy-dispersive X-ray analysis and Fourier-transform infrared analysis.

“…has also synthesized hollow PtCu octahedral nanoalloys for efficient bifunctional electrocatalysts towards oxygen reduction reaction and methanol oxidation reaction [35] . Core‐shell structured Cu@Pt/C catalyst was fabricated by Long and his research group and Cu@Pt/C catalyst exhibited a superior catalytic activity towards MOR with high electrochemically active surface area (74.3 m 2 ⋅ g −1 ) and low charge transfer resistance (22.8 Ω cm −2 ) [36] …”

We show the design of noble Au/Cu bimetallic nanostructures by a gentle solution process. Transmission electron microscopy (TEM), X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS) analysis confirm the presence of both Au and Cu in the Au/Cu bimetallic nanostructures. The Au/Cu catalyst was explored as an efficient electrocatalyst for methanol oxidation with a current density of 5.71 mA/cm2 at 0.46 V.

“…Generally, MOFs are nearly entirely obtained by hydrothermal/solvothermal or by traditional solution-based approaches. Also, the MOF precursor fabrication has been explained in detail in several types of research [ 71 , 72 ]. Herein, our focus will be mainly on the MOF precursor treatment utilized to acquire aimed materials with desired structures and morphologies (like core–shell structures, hollow nanowire array structures, sandwich structures, and 3D hierarchical structures).…”

The core reactions for fuel cells, rechargeable metal–air batteries, and hydrogen fuel production are the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER), which are heavily dependent on the efficiency of electrocatalysts. Enormous attempts have previously been devoted in non-noble electrocatalysts born out of metal–organic frameworks (MOFs) for ORR, OER, and HER applications, due to the following advantageous reasons: (i) The significant porosity eases the electrolyte diffusion; (ii) the supreme catalyst–electrolyte contact area enhances the diffusion efficiency; and (iii) the electronic conductivity can be extensively increased owing to the unique construction block subunits for MOFs-derived electrocatalysis. Herein, the recent progress of MOFs-derived electrocatalysts including synthesis protocols, design engineering, DFT calculations roles, and energy applications is discussed and reviewed. It can be concluded that the elevated ORR, OER, and HER performances are attributed to an advantageously well-designed high-porosity structure, significant surface area, and plentiful active centers. Furthermore, the perspectives of MOF-derived electrocatalysts for the ORR, OER, and HER are presented.
