Abstract

We have found an efficient adsorption feature provided by an NaCaA-85 zeolite for N₂O even at 298 K and at lower pressures: N₂O adsorption capacities of 1.33 mmol g^-1 and 4.69 mmol g^-1 under respective pressures of 0.3 and at 100 Torr, respectively, indicating the best performance among adsorbent materials so far reported. These adsorption peculiarities will pave a new way for developing excellent materials working for adsorption/separation processes of N₂O.
