“…More recently, Jadhav et al prepared UiO-66-PPy and UiO-66-PEDOT nanocomposites via polymerization of pyrrole (Py) and 3,4-ethylenedioxythiophene (EDOT) in the voids of Zr-based MOF (UiO-66) (Figure 4b). [75] These MOF nanocomposite systems were found to possess enhanced electrical conductivity with lowered thermal conductivity, rendering them with potential applications in thermoelectrics. It is believed that the host framework and the conjugated polymers exhibited synergistic interactions, remarkably enhancing the electrical conductivity (≈2 × 10 −2 S cm −1 for UiO-66-PPy and ≈10 −3 S cm −1 for UiO-66-PEDOT compared to neat UiO-66, obtained under four-probe measurements).…”

Thermoelectrics that enable direct heat–electricity conversion possess unique advantages for green and renewable energy revolution and have received rapidly growing attention in the past decade. Among various thermoelectric materials, metal–organic frameworks (MOFs) with intrinsic high porosity and tunable physical/chemical properties are emerging as a promising class of materials that have been demonstrated to exhibit many unique merits for thermoelectric applications. Their structural topologies and thermoelectric properties can be facilely regulated by precisely selecting and arranging metal centers and organic ligands. Besides, a large variety of guest molecules can be incorporated within their pores, giving rise to novel avenues of raising energy‐conversion efficiency. This review focuses on the recent advances in designing conductive MOFs and MOF‐based composites for thermoelectric applications. It first introduces the fundamental thermoelectric parameters and the underlying regulation mechanisms specifically effective for MOFs, then summarizes the related studies conducted in recent years, where the structural design strategies of tuning thermoelectric properties are demonstrated and discussed. In the final part, conclusions and perspectives with the envision of an outlook for this promising area are presented.

“…The method is mainly used for polymerization of polymer monomers in MOF pores. It has many advantages, including mild reaction conditions, a wide range of applicable frameworks, and ease of preparation of porous polymers at the expense of MOF derivatives [228,239,240]. Mashao et al [241] combined polyaniline (PANI) with Co-ZIF by in situ oxidative polymerization to form PANI-CoZIF composites.…”

Gas sensing materials, such as semiconducting metal oxides (SMOx), carbon-based materials, and polymers have been studied in recent years. Among of them, SMOx-based gas sensors have higher operating temperatures; sensors crafted from carbon-based materials have poor selectivity for gases and longer response times; and polymer gas sensors have poor stability and selectivity, so it is necessary to develop high-performance gas sensors. As a porous material constructed from inorganic nodes and multidentate organic bridging linkers, the metal-organic framework (MOF) shows viable applications in gas sensors due to its inherent large specific surface area and high porosity. Thus, compounding sensor materials with MOFs can create a synergistic effect. Many studies have been conducted on composite MOFs with three materials to control the synergistic effects to improve gas sensing performance. Therefore, this review summarizes the application of MOFs in sensor materials and emphasizes the synthesis progress of MOF composites. The challenges and development prospects of MOF-based composites are also discussed.

“…Recently, the Ballav group prepared porous semiconductor composites via assembling PPy and PEDOT links into the cavities of UiO‐66. [ 130 ] Remarkably, due to the essential double porosity in UiO‐66, polymer links were discovered to selectively settle down inside only one void. This led to an extraordinary improvement (million‐fold) of the electroconductivity while this composite could hold 60–70% porosity of its parent MOF.…”

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.
