Fig. 2. SEM images and XRD patterns of MOF-303 membranes fabricated by DS method.

Fig. 2

SEM images of the membrane after (a, b), seeding (the inset in (b) shows an enlarged view of the seeding layer covering the alumina HF substrate), (c, d) 1-h secondary growth, and (e, f) 48-h. a, c, e are surface images, and (b, d, f) are cross-sectional images of the membrane. The red circles in (c) display the intercrystalline gaps. The red dotted lines in (b, d, f) divide the cross-sections into the HF substrate and MOF layer parts. g XRD patterns and CPO ratios of the membrane.
