From: Robust ultrathin nanoporous MOF membrane with intra-crystalline defects for fast water transport
a Low-angle (2.6−20°, λ = 1.541 Å) experimental and simulated XRD patterns of UiO-66 structures with different intra-crystalline defects. b Simulated and experimental relationship between specific surface area and missing-linker defect density. c Defect density comparison between UiO-66 and ML-UiO-66 powders determined by Brunner−Emmet−Teller (BET) and thermogravimetric (TG) results (Supplementary Figs. 24, 25). d EDS spectra of UiO-66 and ML-UiO-66 membrane surface. e Attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) spectra of UiO-66 and ML-UiO-66 membrane. f Liquid 1H Nuclear magnetic resonance (NMR) spectrum of ML-UiO-66 powder. g Structural representations of UiO-66 (defect-free) and ML-UiO-66 (missing-linker defect).
