Here we discuss the removal of nitrogen dioxide, an important toxic industrial chemical and pollutant, from air using the MOF UiO‐66‐NH 2 . The amine group is found to substantially aid in the removal, resulting in unprecedented removal capacities upwards of 1.4 g of NO 2 /g of MOF. Furthermore, whereas NO 2 typically generates substantial quantities of NO on sorbents, the amount generated by UiO‐66‐NH 2 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 NO 2 to molecular nitrogen.
