Recently, low-concentration ammonia (NH3) capture has attracted considerable attention for applications in ammonia–hydrogen fuel cells and confined spaces. The main objective of this study was to develop novel ultramicropore ionic liquid-supported aerogel composites (UILACs), designed effectively expose the multiple hydrogen bonding sites liquid through constructed structure order selectively separate NH3. UILACs achieved a maximum NH3 capacity 164.69 mg NH3/g absorbent at 25 °C 0.10 MPa, which 3.47 times higher than that pure aerogel. In breakthrough experiments with low concentrations (1000–10,000 ppm), exhibited exceptional NH3/H2 NH3/N2 selectivity 2460 10,474, respectively, 1000 ppm NH3, values are 31.5 22.1 These significantly exceeded those aerogels, owing high hydroxyl ammonium (HAIL) loading, interactions between HAIL ultramicropores, as confirmed by density functional theory (DFT) calculations isothermal analysis. Furthermore, maintained stable adsorption performance ten adsorption–desorption cycles, demonstrating UILACs’ potentials efficient separation energy applications.
