“…To meet the rapid mass and electron transport required in harsh electrocatalytic conditions, it is preferred to select chemically stable and conductive MOFs, such as thin sheets or NPs. [75,76] The other option is to encapsulate metal NSs in the confined void space (i.e., cavities or channels) of MOFs, which is much more preferred in many studies. [30] In this case, MOFs offer spatial confinement, not only to stabilize metal NSs, but also to serve as transport pathways for reaction substrates and products.…”

Electrocatalysis is a highly promising technology widely used in clean energy conversion. There is a continuing need to develop advanced electrocatalysts to catalyze the critical electrochemical reactions. Integrating metal active species, including various metal nanostructures (NSs) and atomically dispersed metal sites (ADMSs), into metal–organic frameworks (MOFs) leads to the formation of promising heterogeneous electrocatalysts that take advantage of both components. Among them, MOFs can provide support and protection for the active sites on guest metals, and the resulting host‐guest interactions can synergistically enhance the electrocatalytic performance. In this review, three key concerns on MOF‐metal heterogeneous electrocatalysts regarding the catalytic sites, conductivity, and catalytic stability are first presented. Then, rational integration strategies of MOFs and metals, including the integration of metal NSs via surface anchoring, space confining, and MOF coating, as well as the integration of ADMSs either with the metal nodes/linkers or within the pores of MOFs, along with their recent progress on synergistic cooperation for specific electrochemical reactions are summarized. Finally, current challenges and possible solutions in applying these increasingly concerned electrocatalysts are also provided.

“…The method can effectively restrict the ILs into MOFs structures and provide the possibility of incorporating the ILs with larger ions than pore aperture diameter into the pores of MOFs. [79,80] In this strategy, the choice of MOFs and ILs is crucial for the reason that the guest molecules can separate from the large pores of MOFs while the over-small size prevents the entrance of ILs. On the other hand, a well-selective ligand can provide Lewis acid-base sites, so that a powerful connection between ILs and MOFs can be achieved.…”

Nowadays solid‐state batteries have become a hot spot in the research of batteries and a significant candidate for commercial batteries for the increasing demands for good safety and excellent energy density. Metal‐organic frameworks (MOFs) have been considered as suitable materials for solid‐state electrolytes (SSEs) for the merits of regular channels and large specific surface areas, which can provide a promising structural platform for fast‐ion conduction. Therefore, numerous kinds of MOF‐based SSEs with enhanced electrochemical performance have been successfully synthesized and studied in recent years. In this review, the recent progress (synthesis methods, physical and chemical characteristics) of MOF‐based SSEs for secondary batteries have been summarized. Finally, the challenges and opportunities faced by the future development in this field are put forward, hoping to provide some enlightenment for the synthesis of MOF‐based SSEs, so as to create more efficient, long‐lasting, and safe SSE‐based secondary batteries.

“…This material has exhibited competitive performance as electrode materials for oxygen reduction reactions (The mass-specific activity increase up to 2-fold). In order to ensure the advantage (high specific surface area) of neat nanoparticles, Koikolainen et al selected zeolite imidazolate frameworks (ZIFs) as the porous support for the immobilization of nanoparticles. During the material preparation, the precursor (PdCl 2 ) was solvated by [Bmim][NTf 2 ], which acted as template agents and MW absorber; the released heat under MW irradiation from these ILs induced the formation of Pd nanoparticles with well-defined morphology within 10 min.…”

Progress in microwave (MW) energy application technology has stimulated remarkable advances in manufacturing and high-quality applications of ionic liquids (ILs) that are generally used as novel media in chemical engineering. This Review focuses on an emerging technology via the combination of MW energy and the usage of ILs, termed microwave-assisted ionic liquid (MAIL) technology. In comparison to conventional routes that rely on heat transfer through media, the contactless and unique MW heating exploits the electromagnetic wave−ions interactions to deliver energy to IL molecules, accelerating the process of material synthesis, catalytic reactions, and so on. In addition to the inherent advantages of ILs, including outstanding solubility, and well-tuned thermophysical properties, MAIL technology has exhibited great potential in process intensification to meet the requirement of efficient, economic chemical production. Here we start with an introduction to principles of MW heating, highlighting fundamental mechanisms of MW induced process intensification based on ILs. Next, the synergies of MW energy and ILs employed in materials synthesis, as well as their merits, are documented. The emerging applications of MAIL technologies are summarized in the next sections, involving tumor therapy, organic catalysis, separations, and bioconversions. Finally, the current challenges and future opportunities of this emerging technology are discussed.
