Considering the rapid increase of CO emission, especially from power plants, there is a constant need for materials which can effectively eliminate post-combustion CO (the main component: CO/N = 15/85). Here, we show the design and synthesis of a Cu(II) metal-organic framework (FJI-H14) with a high density of active sites, which displays unusual acid and base stability and high volumetric uptake (171 cm cm) of CO under ambient conditions (298 K, 1 atm), making it a potential adsorbing agent for post-combustion CO. Moreover, CO from simulated post-combustion flue gas can be smoothly converted into corresponding cyclic carbonates by the FJI-H14 catalyst. Such high CO adsorption capacity and moderate catalytic activity may result from the synergistic effect of multiple active sites.
考虑到 CO 排放量的快速增长，特别是来自发电厂的排放量，我们一直需要能够有效去除燃烧后 CO（主要成分：CO/N = 15/85）的材料。在这里，我们展示了一种具有高密度活性位点的 Cu(II) 金属有机骨架（FJI-H14）的设计和合成，它具有异常的酸碱性和稳定性，在环境条件下（298 K，1 atm）对 CO 的体积吸附量高达 171 cm3 cm-3，是一种有潜力的燃烧后 CO 吸附剂。此外，FJI-H14 催化剂可将模拟燃烧后烟道气中的 CO 顺利转化为相应的环状碳酸盐。这种高 CO 吸附能力和适中的催化活性可能源于多个活性位点的协同效应。
