“…The solvothermal (hydrothermal) method is the most mature method for MOF synthesis, and most MOFs are currently synthesized by this method. 116 In the solvothermal method (hydrothermal method), metal salts, organic ligands, and solvents (including mixed solvents) are sealed in the reaction vessel in a certain ratio. The raw materials are dissolved by water or organic solution in the reaction vessel, and MOF crystals are formed by crystallization and precipitation.…”

Metal–organic frameworks (MOFs) as popular nanomaterials have outstanding application prospects in water sorption applications due to their unique structures with excellent properties, such as high porosity, large specific surface area, nanoscale features, reticulation structure, and controllable adjustment of the pore size. Sorbents require high water sorption and water stability to collect, utilize, or remove water. The structure of most MOFs is destroyed upon contact with water, which greatly limits their practical application. This paper summarizes the internal mechanism of water-stable MOFs and describes the optimal design strategy of water-stabilized MOFs based on the structural design of water-stabilized MOFs and the modification of existing MOFs. This review summarizes and analyzes the current typical MOF synthesis and preparation methods. Solutions are proposed for the problems of MOFs in terms of the synthesis mechanism, mass production, and application, and the manufacturing strategies and long-term reliability of MOFs are also prospected. The water sorption mechanism of water-stable MOFs and the influencing factors of water sorption behavior are described, and the optimization strategy of the water sorption performance of MOFs is proposed in terms of the microstructure, surface functional groups, and electron group hybridization. Meanwhile, the current challenges are summarized according to the characteristics of water-adsorbing MOFs, and the future development of MOFs are prospected. It is expected to provide a valuable reference for the research direction of the application of MOFs in water sorption.

“…Various applications have been reported for MOFs, including gas storage/separation, catalysis, drug delivery, and detection with electrochemical applications, which can be attributed to the electrochemical performance of metal ions and the ordered porous framework. Various types of MOFs are synthesized at high temperature, high pressure, or with organic solvents, which not only increases the cost of fabrication but also makes large-scale production difficult [ 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ]. The synthesis of mixed-valence Ce-MOFs occurs rapidly at an ambient temperature in aqueous solution, saving considerable time and energy costs [ 54 , 55 ].…”

An ultrasensitive and selective voltammetric sensor with an ultratrace-level detection limit is introduced for ketoconazole (KTC) determination in real samples using a modified carbon paste electrode with a sheaf-like Ce-BTC MOF nanostructure and ionic liquid. The as-synthesized nanostructure was characterized by several techniques, including energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and field emission scanning electron microscopy (FE-SEM). The electrocatalytic performance of the developed electrode was observed by cyclic voltammetry (CV), differential pulse voltammetry (DPV), linear sweep voltammetry (LSV), and chronoamperometry. The limit of detection (LOD) of the developed sensor for KTC is 0.04 μM, and the response was found to be in the dynamic concentration range of 0.1–110.0 μM in a phosphate buffer solution. The proposed electrode exhibits acceptable electrocatalytic activity for KTC oxidation with a high sensitivity of 0.1342 μA·μM−1. The ability of the fabricated sensor to monitor KTC in real aqueous samples is demonstrated using standard addition data.

“…Metal organic frameworks (MOFs), as inorganic‐organic hybrid materials with a periodic network structure, have a huge advantage over classical zeolite molecular sieves. Benefiting from the advantages such as rich chemical composition, large specific surface area, and structural diversity, MOFs have been used in many fields including adsorption, separation, catalysis, sensing, and batteries 1–4 . Among them, ZIF‐8 (zeolitic imidazolate frameworks) formed by zinc and imidazole or its derivative ligands has attracted much more attention due to its robust synthesis protocol and potential advantages in separating small gases 5,6 .…”

The sintering temperature of ZnO ceramic hollow fibers (HFs) is generally up to 1400°C and presents a major challenge to obtain HFs with high permeability and mechanical strength at lower sintering temperature. This work proposed a glass powder‐assisted method to reduce the sintering temperature by using their adhesive property. ZnO‐glass composite HFs with longer finger‐like channels, high permeability (3.12 × 10−5–9.1 × 10−6 mol·m−2·s−1·Pa−1) and good mechanical strength (42.12–52.75 MPa) were obtained at sintering temperature of 1150°C. More glass powders can generate stronger bonding effect during the ZnO particles, resulting in a decrease in porosity and an increase in the mechanical strength of ZnO‐HF. These ZnO‐HFs were further applied for inducing ZIF‐8 membranes by one‐step solvothermal growth. ZnO not only provides the growth and nucleation centers but also acts as transitional bridge to make the ZIF embed into support to improve the bonding force between membrane and support. Therefore, HF‐supported‐ZIF‐8 membrane exhibited both mechanical and thermal robustness by maintaining their gas separation performance during the 30‐min sonication treatment and 50‐h operation testing at 25–200°C. Furthermore, this membrane provided good reproducibility. This work opens prospects for preparing ceramic HFs at lower sintering temperature and their functional applications as well as the preparation of MOF membranes.
