One effective approach to addressing the imminent water shortage crisis is sorption-based atmospheric water harvesting (SAWH). Covalent organic frameworks (COFs) are a type of porous crystalline material. Due to its unique structural characteristics, it can show broad application prospects in the fields of gas storage and separation, catalysis, optoelectronic materials, and atmospheric water harvesting. Then, we summarize recent advances in using COF-based sorbents for atmospheric water harvesting and briefly introduce the technology of atmospheric water collection and the application of COFs in the field of sorption-based atmospheric water harvesting (SAWH).展开更多

The results show that the organic salt exhibits good stability and high proton conductivity, and the value can be reached as high as 4.4 × 10−3 S∙cm−1 under 45˚C and 100% RH conditions. Meanwhile, the organic salt is easy to synthesize, combining with the high proton conductivity, it will have a perspective application in fuel-cell technology.展开更多
