“…Unlike other porous materials, such as metal–organic frameworks and porous metal oxides, the fabrication of COFs avoids the involvement of metal ions, thus preventing the possibility of secondary pollution caused by the release of metal ions. Therefore, they have been widely used in catalysis, − photocatalysis, − gas adsorption/separation, energy storage, − drug delivery, and environmental remediation. − …”

The insolubility in solvents and poor processability of powder covalent organic frameworks (COFs) considerably impede their practical application. To address these issues and bridge the gap between powder COFs and their practical application, the construction of monolithic COFs has emerged as a feasible and effective solution. Monolithic COFs (i.e., macroscopic three-dimensional architectures) with hierarchical structures have attracted tremendous interest for environmental remediation and exhibited good contaminant removal performances owing to their wide distribution of pore sizes ranging from micropores to macropores, large specific surface area, tailored chemical components, and excellent chemical stability. Monolithic COFs can be either pure COFs with self-supporting structures or composites of COFs with other materials. The resulting COF-based monoliths inherit the merits of the parent powder COFs (such as tunable pore size, tailored structure, and super chemical/thermal stability) and the intriguing features of monolithic materials, such as hierarchical structure, high porosity, and easy handling, endowing them with fast mass transfer and high adsorption capacity. This review provides a comprehensive summary of the recent advances in the synthesis of monolithic COF materials. Additionally, the recent progress of their application in environmental remediation is summarized, including metal-ion removal, organic-pollutant capture, and oil–water separation. Furthermore, this review discusses the current challenges and provides future perspectives. We sincerely hope that it will contribute to the further development of COF-based materials in other fields, especially environmental remediation.

Inspired by cell membranes, with high efficiency and precision separation for water and ions, development of biomimetic membranes using two-dimensional (2D) materials and responsive molecules/macromolecules has been emerging. Herein, this review overviews the recent development of biomimetic 2D composited membranes integrating 2D materials and the responsive subunits for water and ion separation. The review highlights the design concepts and various fabrication strategies, such as coating, layer-by-layer (LBL) assembly, electrochemical deposition, and filtration. The biomimetic 2D composited membranes are preliminarily achieved for adjustable ion separation and desalination. The challenges with biomimetic 2D composite membranes are also discussed, including the intricate mass transfer mechanisms and stability during operation. With the exceptional functionalities offered by angstrom-scale 2D nanochannels, biomimetic 2D composite membranes hold great potential in shaping the future of cutting-edge separating membranes, opening new avenues for advanced separation technologies.
