rather than obtained from maritime brines or secondary sources such as spent energy storage devices, owing to the difficulties in Li recovery. Herein, we present a porous organic polymer capable of capturing Li ions from aqueous solutions through highly pre-organized, heterocyclic crown ether-like pores in the polymer backbone. These features enable Li+ uptake capacities over 120 mg g−1 and selectivity
锂 (Li) 是 21 st 世纪的重要资源。尽管如此,由于
锂回收困难,
锂传统上是开采的,而不是从海洋盐
水或废储能设备等二次来源中获取。在此,我们提出了一种多孔有机聚合物,能够通过聚合物主链中高度预组织的杂环
冠醚状孔从
水溶液中捕获
锂离子。这些特性使 Li + 的吸收能力超过 120 mg g −1 ,并且相对于 Na + 、Ca 2+ 等高度竞争性离子具有选择性。和
镁 2+ 。
