“…Compared with traditional inorganic porous catalyst and nanometer catalyst, MOFs with evenly dispersed catalytic sites, large specific surface area, etc., offer better catalytic performances. [ 164–167 ] It is feasible to design MOFs with different hierarchies and rich polarity/catalytic sites. For example, the Jiang group has developed an aluminum‐based porphyrinic MOF (Al‐TCPP) to stabilize a single platinum site through strong chemical affinity with pyrrolic N atom, [ 168 ] which provide highly effective charge transfer tunnels and thereby possess potential application in electrocatalysis ( Figure a).…”

Metal‐sulfur batteries (MSBs) are considered up‐and‐coming future‐generation energy storage systems because of their prominent theoretical energy density. However, the practical applications of MSBs are still hampered by several critical challenges, i.e., the shuttle effects, sluggish redox kinetics, and low conductivity of sulfur species. Recently, benefiting from the high surface area, regulated networks, molecular/atomic‐level reactive sites, the metal‐organic frameworks (MOFs)‐derived nanostructures have emerged as efficient and durable multifaceted electrodes in MSBs. Herein, a timely review is presented on recent advancements in designing MOF‐derived electrodes, including fabricating strategies, composition management, topography control, and electrochemical performance assessment. Particularly, the inherent charge transfer, intrinsic polysulfide immobilization, and catalytic conversion on designing and engineering of MOF nanostructures for efficient MSBs are systematically discussed. In the end, the essence of how MOFs’ nanostructures influence their electrochemical properties in MSBs and conclude the future tendencies regarding the construction of MOF‐derived electrodes in MSBs is exposed. It is believed that this progress review will provide significant experimental/theoretical guidance in designing and understanding the MOF‐derived nanostructures as multifaceted electrodes, thus offering promising orientations for the future development of fast‐kinetic and robust MSBs in broad energy fields.

With the development of modern industry, global warming is becoming a challenging issue due to the emissions of large quantities of greenhouse gases, mainly carbon dioxide (CO2). The conversion of CO2 to useful compounds is considered as an effective and economic way to solve such a climate problem. Metal‐organic frameworks (MOFs) are an emerging class of porous crystalline materials that have shown great potential in the conversion of CO2. The advantages of MOFs in CO 2 conversion lie in their high surface areas, adjustable pore size, and high porosity. More importantly, desirable functional sites can be easily designed and precisely installed to the pore wall of target MOFs by pre‐assembly and/or post‐synthetic modification (PSM) ways. This review summarizes the recent advances in constructing MOF catalysts for the application in CO2 conversion. We believe that the design and synthesis of MOF catalysts for CO2 conversion can be a promising way to solve the “greenhouse effect”.

“…However, CO 2 is a very inert chemical owing to the high energy C=O bonds (806 kJ mol −1 ). Meanwhile, the electrochemical CO 2 RR is companied by HER, which can decrease the Faradaic Efficiency of CO 2 RR [103] . Therefore, electrocatalysts that can active C=O as well as prohibited HER catalytic activity is very attractive for CO 2 RR [104]…”

Single-atom catalysts (SACs) have attracted increasing research interests owing to their unique electronic structures, quantum size effects and maximum utilization rate of atoms. Metal organic frameworks (MOFs) are good candidates to prepare SACs owing to the atomically dispersed metal nodes in MOFs and abundant N and C species to stabilize the single atoms. In addition, the distance of adjacent metal atoms can be turned by adjusting the size of ligands and adding volatile metal centers to promote the formation of isolated metal atoms. Moreover, the diverse metal centers in MOFs can promote the preparation of dual-atom catalysts (DACs) to improve the metal loading and optimize the electronic structures of the catalysts. The applications of MOFs derived SACs and DACs for electrocatalysis, including oxygen reduction reaction, oxygen evolution reaction, hydrogen evolution reaction, carbon dioxide reduction reaction and nitrogen reduction reaction are systematically summarized in this Review. The corresponding synthesis strategies, atomic structures and electrocatalytic performances of the catalysts are discussed to provide a deep understanding of MOFs-based atomic electrocatalysts. The catalytic mechanisms of the catalysts are presented, and the crucial challenges and perspectives are proposed to promote further design and applications of atomic electrocatalysts.
