Abstract

Air pollution by nitrogen oxides, NO_x, is a major problem, and new capture and abatement technologies are urgently required. Here, we report a metal–organic framework (Manchester Framework Material 520 (MFM-520)) that can efficiently confine dimers of NO₂, which results in a high adsorption capacity of 4.2 mmol g^–1 (298 K, 0.01 bar) with full reversibility and no loss of capacity over 125 cycles. Treatment of NO₂@MFM-520 with water in air leads to a quantitative conversion of the captured NO₂ into HNO₃, an important feedstock for fertilizer production, and fully regenerates MFM-520. The confinement of N₂O₄ inside nanopores was established at a molecular level, and the dynamic breakthrough experiments using both dry and humid NO₂ gas streams verify the excellent stability and selectivity of MFM-520 and confirm its potential for precious-metal-free deNO_x technologies.
