Nitrous oxide (N2O) is a potent greenhouse gas and major contributor to ozone depletion. Its primary industrial emission source tail from adipic acid production, which typically comprises mixture of N2O, CO2, N2, O2. Current technologies for the removal N2O CO2 are energy-intensive operationally complex. Herein, first time, simultaneous capture quaternary achieved using Ni(II)-pyrazolecarboxylate framework, BUT-167. This material demonstrated an exceptional adsorption capacity (135.8 cm3 cm-3 at 40 kPa) high packing density (790 mg cm-3) outperforming reported sorbents. Moreover, BUT-167 also exhibits remarkable (101.5 4 kPa), achieving simultaneously selectivity values 257.6 CO2/N2 (4:96, v/v) 135.7 N2O/N2 (40/60). Importantly, robust outstanding dual-gas performance across multiple adsorption-desorption breakthrough cycles under both dry humid conditions. The strong affinity toward could be attributed hydrogen bonding interactions facilitated by its highly confined channel structure, as confirmed through single-crystal X-ray diffraction analysis.
