Abstract The excessive emission of greenhouse gases, which leads to global warming and alarms the world, has triggered a campaign for carbon neutrality. Carbon capture sequestration (CCS) technology aroused wide research interest as versatile mitigation technology. Metal–organic frameworks (MOFs), new class high‐performance adsorbents, hold great potential CO 2 from large point sources ambient air due their ultra‐high specific surface area well pore structure. In recent years, MOFs have made progress in field separation, published number important results, greatly promoted development MOF materials practical applications. This review summarizes most advanced on various application scenarios over past six years. strategies enhancing selective adsorption separation are described detail, along with MOF‐based composites. Moreover, this also systematically highly concerned issues applications capture. Finally, future by is prospected.

ConspectusCarbon capture is an indispensable step toward closing the anthropogenic carbon cycle. However, large-scale implementation of conventional thermochemical technologies hindered by their low energy efficiency, limited sorbent stability, and complexity in infrastructure integration. A mechanistically different alternative, commonly known as electrochemically mediated (EMCC), has garnered increasing research traction over past few years relies on electrochemical stimuli instead thermal or pressure swings for release dioxide (CO2). Compared to methods, EMCC can be operated under mild conditions driven intermittent renewable sources a flexible design meet multiscale demands capture, offering potentially sustainable, energy-efficient, cost-effective solution CO2 concentration from dilute mixtures ambient environment.Nanomaterials have played crucial role research. For instance, nanoporous materials provide increased free volumes, surface areas, active sites through physical chemical adsorption gaseous phase. In contrast, absorption via acid–base interactions using solubilized electrolytes. Therefore, most sorbents mediators explored so far been developed molecules rather than nanomaterials. recent years, our team focusing electrifying processes at molecular, materials, process levels. We seek address pressing issues associated with EMCC, either fixed-bed flow systems, that prevent practical use. These include parasitic reactions molecular oxygen, insufficient electrode capacity utilization, crossover, etc. To these problems, there urgent need develop rationally designed nanomaterials interface electrochemistry device engineering. This Account provides overview progress developing new chemistries engineering batch/continuous EMCC. discuss limitations current technology emphasize why are critical capture. First, we introduce principles based redox-active organic carriers metrics performance evaluation. Second, showcase how tackle problems solubility, oxygen electrolyte compatibility Third, early results solid nonswelling membranes high-surface-area gas–liquid contactors. Finally, building foundation established prior work, offer perspectives future directions help challenges
