Through electrochemical strategy to control the ligand of protons and exchange process, so as to realize the zero defect of multi-core cluster MOFs controlled assembly, membrane distillation layer
were nine with different metal clusters and/or organic ligand reticular fcu - MOF membrane distillation. The fumaric acid (fum) membrane distillation Zr - fum - fcu - MOF and Y - fum - fcu - MOF
jacketed glass reactor showed excellent C3H6 / C3H8 and butane isobutane nC4 / iC4 efficient separation of mixtures. The
membrane distillation in as much as the actual feed pressure of 7 ATM, for the separation of mixture of C3H6 / C3H8 provides high selectivity and excellent stability.
Six nuclear membrane distillation synthesis: (a) the design of the clusters in three different forms, RE/Zr, C, O and H, respectively, with the light/dark blue, gray, red and white; (b) extension
fcu network, including octahedral cage said with a yellow ball tetrahedron cage is surrounded by pink triangle; (c) as the object of molecules and molecular sieve the only entrance triangular hole
sketch; (d) adjust fcu - MOFs aperture size of three kinds of commonly used strategies; (e) MBBs top-down isolation for structural analysis, and each MBB reassemble from bottom to top, with the
help of the external current were continuous, good polycrystalline layer; Explore synthetic RE - fcu - MOF (f) and Zr - fcu - MOF (g) the best condition of membrane distillation, including boundary
cbd centrifugal extractor conditions with different color tag: purple
amorphous layer, deep blue said crack layer, green said successive layers, buff said discrete layers, gray said amorphous layer.
XRD diffraction pattern (a) when using the dilute solution (5 mM) clusters Y - fum - fcu - the top view of the MOF layer; When clusters concentration on the 15 mm in 4:1 (b), 5.6:1 (c), 1 (d) and
(e) and under different ligand - clusters than Y - fum - fcu - the top view of the MOF layer; Clusters (f) ligand - 5.6:1 - fum - fcu - Y of cross-sectional images MOF membrane distillation; (g)
was prepared under different conditions of Y - fum - fcu - MOF membrane distillation of XRD diffraction pattern; Other eight fcu - MOF membrane distillation (illustration) : cross section SEM
figure and the vertical Zr - fum - fcu - MOF film (h), Y - mes - fcu - MOF membrane (I), Zr - mes - fcu - MOF membrane (j), Y - tpa - fcu - MOF membrane (k), Zr - tpa - fcu - MOF
hemp extraction centrifuge membrane (l), Y - naph - fcu - MOF membrane (m), Zr - naph - fcu -
MOF membrane (n) and Y - aminotpa - fcu - MOF membrane (o).
Different MOFs membrane distillation of C3H6 / C3H8 and nC4 / iC4 (a) (b) such as Moore mixture separation performance, including Zr - fum - fcu - been nine times the MOF membrane distillation
experiments, Y - fum - fcu - thin MOF。
