Covalent organic frameworks (COFs) are an emerging type of porous crystalline material with highly ordered aperture size and tunable structures with designer properties. COFs have been proposed as promising materials for water treatment because of their notable intrinsic properties like excellent chemostability, high surface area, abundant functional sites, and uniform adjustable aperture size. This review focuses on fundamental COF design principles for water treatment (stability, aperture size, and surface functionalization) and the state‐of‐the‐art application of COFs in desalination, organic contaminant sorption, and ion capture. Additional potential promising applications of COFs for water treatment, including solar steam generation, photocatalysis for degradation of organic contaminants, and capacitive deionization are also presented along with an outlook toward future opportunities in the field.

The structural details of carbon materials directly affect their properties as an electrode material, such as specific capacitance and coulomb efficiency. Therefore, the structural analysis of carbon materials has always been an important step in the mechanistic insight into their roles in electrochemical energy storage. Raman spectroscopy, as molecular spectroscopy technique, has been widely used in understanding the lattice vibration mechanics of carbon materials and providing information on the chemical structure at molecular level, as well as microstructure analysis of carbon materials. In addition, the development of correlative-Raman technology enables clarifying more comprehensive and accurate structural information for carbon-based materials. With this information, it is of great significance to guide the construction of advanced carbon-based electrode materials for energy storage.

“…Most of these carbon fibers have a decent mechanical strength for mechanized processing, such as knitting and weaving while maintaining flexibility for arbitrary deformation. These merits allow a complex textile structure design and further decoration to achieve a desired porous morphology for different applications, such as flexible energy devices and wearable electronics (Xu et al, 2018 ; Zheng et al, 2020 ).…”

Animal silk-derived carbon materials are of interest to various applications, such as smart cloth and wearable sensors. However, it remains a challenge to massively transform silks into continuous carbon fibers. In this work, carbon fibers based on two kinds of animal silks, i.e., Bombyx mori (B. mori) silk and Antheraea pernyi (A. pernyi) silk, are prepared by using a large-scale-capable one-step heating process without any additives or activation process. These carbon fibers and yarns are electroconductive and mechanically robust. To expand the application of these carbonized silks, we further weaved them with cotton yarns to obtain composite fabrics with different textures and evaluated their performance for solar steam evaporation. Our results confirmed that the advantages of these composite fabrics in light absorption, large surface area, and hierarchical liquid transport channels allowed them to be used as a solar steam generation for desalination and sewage treatment. In addition, we reported that these conductive carbon fibers could be assembled into fluidic nanogenerators to generate electricity from the water flow. This work is expected to guide a large-scale preparation and use of animal silk-derived amorphous carbon fibers.
