Layered double hydroxides (LDHs) membranes with structured galleries formed by metal cations and anions have gained significant attention for diverse applications. Understanding mass transport mechanisms is crucial for effective membrane design and enhanced separation processes. This review explores strategies for creating continuous LDHs membranes and summarizes the selective transport of gases, liquids, and ions, as well as current challenges and future perspectives.
Layered double hydroxides (LDHs) consist of metal cations with positive charges and anions located between their layers, resulting in a structured gallery height and a wide array of surface functionalities. In recent years, LDHs have garnered substantial attention due to their expanded application range through the development of LDHs membranes, bringing exciting possibilities across various fields. A deep understanding of mass transport mechanisms is essential for designing membrane materials effectively and enhancing separation processes. In this review, In this review, the strategies employed for creating continuous and well-intergrown LDHs membranes are first elaborated. Subsequently, the study delves into a detailed discussion of the selective transport processes involving gas molecules, liquid molecules, and ions through LDHs membranes. Based on the interactions between permeated molecules and LDHs membranes, the mass transport mechanisms can be concluded in molecular sieving mechanism, solution-diffusion mechanism and facilitated transport mechanism. Finally, the current challenges and future perspectives are outlined. Layered double hydroxides (LDHs) membranes, featuring structured galleries with metal cations and anions, have gained significant attention for diverse applications. Understanding mass transport mechanisms is crucial for effective membrane design and enhanced separation processes. This review explores strategies for creating continuous LDHs membranes and summarizes selective transport for gases, liquids, and ions, current challenges and future perspectives.image
