An efficient strategy for the high-capacity capture of CO is reported, and a phase change in protic chlorocuprate ionic liquids (PCILs) from liquid to solid is found during CO absorption. The highest CO capacity is 0.96 molCO molIL-1, being at least 150 times higher than that in [BMIM][PF6]. Both absorption and membrane permeation reveal that the PCILs are potential for the selective separation of CO from N2.
报道了一种高效捕获 CO 的策略，在 CO 吸收过程中发现质子化氯铜离子液体（PCILs）从液态向固态发生相转变。最高 CO 容量为 0.96 molCO molIL-1，至少比 [BMIM][PF6]高 150 倍。吸收和膜渗透都表明 PCILs 有望从 N2 中选择性分离 CO。
