dc.description.abstract | The search for more efficient and selective solid adsorbents towards carbon capture, particularly in trace CO2 concentration, remains a significant challenge. Here, we present the synthesis of nanocrystalline sodium gismondine (Na-GIS) with Si/Al = 2.5 and potassium chabazite (K-CHA) zeolites with Si/Al = 2.0 using L-lysine as a crystal growth inhibitor. Na-GIS nanozeolites were found to show a CO2 uptake as high as 0.70 mmol g−1 under direct air capture (DAC) conditions (i.e., 298 K and 400 ppm CO2), about 18 times greater than that of microcrystalline Na-GIS, together with high adsorbent stability. Such behavior was also observed for Na-CHA nanozeolites, although the extent of increase (0.47 vs 0.13 mmol g−1) was smaller compared to the microcrystalline counterpart. This study demonstrates that the introduction of nanocrystallinity into small-pore zeolites without losing intrinsic microporosity is a viable route to the development of more efficient zeolite-based DAC adsorbents. © 2023 Elsevier B.V. | - |
