“…In the thermal solvent method, zinc salt and 2‐methylimidazole (Hmim) were dissolved in different molar ratios in different solvents and were carried out in different conditions of temperature and time. Zinc salt could be Zn(NO 3 ) 2 · 6H 2 O, Zn(NO 3 ) 2 · 4H 2 O, Zn(CH 3 COO) 2 · 2H 2 O, ZnCl 2 , or Zn(OH) 2 . The zinc salt to Hmim molar ratio (Zn:Hmim) is often taken excessively (1:4–1:6), and in some studies, the Hmim seemed to be extremely high (1:56–1:70) …”

“…Common solvents used for ZIF‐8 preparation were dimethylformamide (DMF), methanol, methanol and NH 4 OH, methanol and HCOONa, water, water and surfactant, or a series of solvents such as ethanol, n ‐propanol, 2‐propanol, n ‐butanol, 2‐butanol, n ‐octanol, and acetone . Generally, ZIF‐8 synthesized in a less toxic solvent usually employed a largely excess amount of Hmim.…”

This article systematically presented analysis results of factors affecting the preparation of nano‐ZIF‐8 in methanol for high yield. Samples were characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Brunauer‐Emmett‐Teller (BET) adsorption, and thermogravimetry‐differential thermal analysis (TG/DTA). Synthesized nano‐ZIF‐8 had advantages over commercial ZIF‐8 (Basolite® Z1200 from Sigma‐Aldrich) such as a higher surface area, consisting of not only micropores like Basolite® Z1200 but also subordinate mesopores, formed by an assembly of nano‐ZIF‐8 crystals, which was 30 nm. Specifically, for the first time, nano‐ZIF‐8 was prepared in methanol with the yield of 61.2 %.

Clean water scarcity is becoming an increasingly important worldwide issue. The water treatment industry is demanding the development of novel effective materials. Defect engineering in nanoparticles is among the most revolutionary of technologies. Because of their high surface area, structural diversity, and tailorable ability, Metal‒Organic Frameworks (MOFs) can be used for a variety of purposes including separation, storage, sensing, drug delivery, and many other issues. The application in wastewater treatment associated with water stable MOF‒based materials has been an emerging research topic in recent decades. Defect engineering is a sophisticated technique used to manufacture defects and to change the geometric framework of target compounds. Since MOFs have a series of designable structures and active sites, tailoring properties in MOFs by defect engineering is a novel concept. Defect engineering can excavate hidden active sites in MOFs, which can lead to better performance in many fields. Therefore, this technology will open new opportunities in water purification processes. However, there has been little effort to comprehensively discuss this topic. In this review, we provide an overview of the development of defect engineered MOFs for water purification processes. Furthermore, we discuss the potential applications of defect engineered materials.
