Here we discuss the removal of nitrogen dioxide, an important toxic industrial chemical and pollutant, from air using the MOF UiO-66-NH2 . The amine group is found to substantially aid in the removal, resulting in unprecedented removal capacities upwards of 1.4 g of NO2 /g of MOF. Furthermore, whereas NO2 typically generates substantial quantities of NO on sorbents, the amount generated by UiO-66-NH2 is significantly reduced. Of particular significance is the formation of a diazonium ion on the aromatic ring of the MOF, and the potential reduction of NO2 to molecular nitrogen.
在这里，我们讨论了使用 MOF UiO-66-NH2 从空气中去除二氧化氮，这是一种重要的有毒工业化学物质和污染物。我们发现，胺基基团在去除过程中起到了很大的作用，使得 MOF 的去除容量达到了前所未有的 1.4 g 的 NO2 / g 的 MOF。此外，虽然 NO2 通常在吸附剂上产生大量的 NO，但 UiO-66-NH2 产生的量却明显减少。特别重要的是，MOF 芳环上形成了重氮离子，以及将 NO2 还原为分子氮的潜力。
