“…The NPC exhibits a comparable ORR activity, higher stability, and better tolerance to methanol compared with the commercial Pt/C. The density functional theory results show that N-doped carbon along with the defects is more favorable for ORR compared with N-doped carbon because the presence of FIGURE 12 | (A) Fe-porphyrin-based (Hemin)-modified UiO-66 (UiO-66@Hemin) made by defective UiO-66 (Shimoni et al, 2019).

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.

Metal‐organic frameworks (MOFs), typically constructed with metallic nodes and organic linkers, have influenced the development of modular solid materials. Their adjustable molecular structure provides a remarkable variety of MOF‐based solid‐state structures towards diverse applications. However, the low conductivity of traditional MOFs extremely hinders their applications in electronic and electrochemical devices. The emerging conductive MOFs, generally possessing two‐dimensional layered structures, are endowed with both the structural merits of common MOFs and exceptional electronic/ionic conductivities. Besides, the selection and optimization of ligands and metal centers, as well as synthetic methods enormously affects the intrinsic conductivity of conductive MOFs. The distinctive crystal structures and superb conductivity promise their appealing applications in electrochemical energy‐related fields. In the review, we mainly summarize representative crystal features, conducting mechanisms and recent advances in rational design and synthesis of conductive MOFs, along with their versatile applications as electrodes for electrochemical capacitors and rechargeable batteries, and as catalysts towards electrocatalysis. Finally, the involved challenges and future trends/prospects of the conductive MOFs for electrochemical energy‐related applications are further proposed.

“…As an outcome of these mentioned virtues, over the passed two decades, MOFs have attracted great attention from the scientific community due to the scope of using either pristine MOFs or MOFderived materials in various important applications. They have also been extensively evaluated as highly promising candidate materials for the design of efficient renewable energy based electrochemical devices e.g., supercapacitors, batteries, and electrocatalysis [5,17,[20][21][22][23].…”

In recent years, we are witnessing a substantially growing scientific interest in MOFs and their derived materials in the field of electrocatalysis. MOFs acting as a self-sacrificing template offer various advantages for the synthesis of carbon-rich materials, metal oxides, and metal nanostructures containing graphitic carbon-based materials benefiting from the high surface area, porous structure, and abundance of metal sites and organic functionalities. Yet, despite recent advancement in the field of MOF-derived materials, there are still several significant challenges that should be overcomed, to obtain better control and understanding on the factors determining their chemical, structural and catalytic nature. In this minireview, we will discuss recently reported advances in the development of promising methods and strategies for the construction of functional MOF-derived materials and their application as highly-active electrocatalysts for two important energy-related reactions: nitrogen reduction to produce ammonia, and CO2 reduction into carbon-based fuels. Moreover, a discussion containing assessments and remarks on the possible future developments of MOF-derived materials toward efficient electrocatalysis is included.
