Regulating Adsorption Behaviors in Crystalline Porous Materials by External Electric Fields

The regulation of adsorption behaviors in crystalline porous materials (CPMs) using external electric fields (E‐fields) is an emerging field. CPMs are highly valued for their large surface area, well‐ordered pore structures, and chemical versatility, making them ideal for applications in adsorption/separation, catalysis, and biomedicine. In this review, the mechanisms underlying the E‐field‐induced structural and functional modifications in CPMs, such as phase transitions, framework distortions, and alterations in pore accessibility and selectivity, are delved into. Through a comprehensive analysis, the adsorption behaviors influenced by E‐field regulation are classified into three main categories: selective molecular adsorption, selective ion adsorption, and the diffusion/transportation of molecules and ions. Furthermore, in this review, the current landscape of research in this area, highlighting the challenges and future directions for developing E‐field‐regulated adsorbents is critically assessed. In this work, it is aimed to summarize recent advances and identify gaps in the understanding of E‐field effects on CPMs, providing a foundation for the rational development of next‐generation materials with E‐field modulated functionalities.
