Fig. 3: Single-component adsorption properties of ZU-61 and Zeolite NaY.

Adsorption isotherms of pX and mX on ZU-61, SIFSIX-2-Cu-i, and zeolite NaY at 333 K in two pressure regions, 0–7 mbar (a) and 0–0.06 mbar (b). The comparison of pX, mX, oX, and EB adsorption behavior on ZU-61 (c) and cycle adsorption of pX on ZU-61 (d) at 333 K.
