“…Therefore, some studies have reported that decorating COFs with Ils is beneficial for obtaining excellent performance for CO 2 removal. [89][90][91][92] For example, a novel allyl-imidazolium IL-modified acylhydrazone-linked COF (COF-IL) exhibited a highly selective CO 2 adsorption (Figure 4c). Jiang et al implemented a geometric transformation strategy to convert fluorinated covalent triazine framework (FCTF-1) from 2D to 0D (Figure 4d).…”

Membrane‐based carbon dioxide (CO2) capture and separation technologies have aroused great interest in industry and academia due to their great potential to combat current global warming, reduce energy consumption in chemical separation of raw materials, and achieve carbon neutrality. The emerging covalent organic frameworks (COFs) composed of organic linkers via reversible covalent bonds are a class of porous crystalline polymers with regular and extended structures. The inherent structure and customizable organic linkers give COFs high and permanent porosity, short transport channel, tunable functionality, and excellent stability, thereby enabling them rising‐star alternatives for developing advanced CO2 separation membranes. Therefore, the promising research areas ranging from development of COF membranes to their separation applications have emerged. Herein, this review first introduces the main advantages of COFs as the state‐of‐the‐art membranes in CO2 separation, including tunable pore size, modifiable surfaces property, adjustable surface charge, excellent stability. Then, the preparation approaches of COF‐based membranes are systematically summarized, including in situ growth, layer‐by‐layer stacking, blending, and interface engineering. Subsequently, the key advances of COF‐based membranes in separating various CO2 mixed gases, such as CO2/CH4, CO2/H2, CO2/N2, and CO2/He, are comprehensively discussed. Finally, the current issues and further research expectations in this field are proposed.

“…Electric field-assisted persulfate activation, as an electro-Fenton-like technology, has attracted increasing attention due to its high efficiency in generating ROS for effective pollutant removal. , In the electro-persulfate membrane system, the cathode, as the electron provider, transfers electrons to PMS, contributing to the activation of PMS to generate ROS. The Fenton-like catalysts loaded on the surface of the carbon base can further improve the PMS activation rate for ROS generation.…”

Electro-Fenton-based membrane (EFM) technologies are promising for removing micropollutants in wastewater bearing several benefits such as minimized chemical input, accelerated reactive oxygen species (ROS) generation, and improved ROS utilization efficiency, thanks to the enhanced mass transfer and effectively enlarged electroactive area. However, the complex mechanism and synergies between electro-Fenton reactions and membrane confinement remain unclear; gaining such information would be much beneficial for rational catalyst/membrane design, system optimization, and further application in actual water conditions. In this Perspective, we systematically describe the membrane compositions, multiple reaction pathways, and advances in EFM systems. Then, we proposed some promising hybrid systems that exhibit great synergies in maximizing purification efficiency. Finally, this perspective provides a roadmap for the future development of EFM systems with low cost and high efficiency by outlining the advanced membrane material design, coupling processes, and integrated device design.

Future renewable energy supply and green, sustainable environmental development rely on various types of catalytic reactions. Copper single‐atom catalysts (Cu SACs) are attractive due to their distinctive electronic structure (3d orbitals are not filled with valence electrons), high atomic utilization, and excellent catalytic performance and selectivity. Despite numerous optimization studies are conducted on Cu SACs in terms of energy conversion and environmental purification, the coupling among Cu atoms–support interactions, active sites, and catalytic performance remains unclear, and a systematic review of Cu SACs is lacking. To this end, this work summarizes the recent advances of Cu SACs. The synthesis strategies of Cu SACs, metal–support interactions between Cu single atoms and different supports, modification methods including modification for carriers, coordination environment regulating, site distance effect utilizing, and dual metal active center catalysts constructing, as well as their applications in energy conversion and environmental purification are emphatically introduced. Finally, the opportunities and challenges for the future Cu SACs development are discussed. This review aims to provide insight into Cu SACs and a reference for their optimal design and wide application.
