B[China has recently made a series of progress in the field of uranium extraction materials from seawater: for the first time, discrete molecular topology design was introduced into a porous organic cage system and the phosphoric acid functionalized material PhosCage was synthesized] September 2, according to the Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences, the research team of the institute has recently made a series of progress in the field of uranium extraction materials from seawater. For the first time, the team introduced discrete molecular topology design into a porous organic cage system, synthesized the phosphoric acid functionalized material PhosCage, and further combined it with aramid nanofibers to prepare composite airgel microspheres AC-POC with high selectivity, high capacity and anti-biofouling capabilities. Relevant results were published in the international academic journals "Journal of Hazardous Materials" and "Separation and Purification Technology". The Qingdao Institute of Energy Research team proposed a discrete molecular topology design strategy to directionally construct phosphoric acid adsorption clusters in the interlayer nanospace of porous organic cages, and prepared the first phosphoric acid functionalized porous organic cage material - PhosCage. Under laboratory conditions, PhosCage can reach adsorption equilibrium in just 5 minutes; in real seawater samples from multiple sea areas, its maximum uranium extraction capacity reaches 50.4 mg/g, which is 8.4 times the relevant benchmark of the U.S. Department of Energy.
