Metal‐Organic Framework MIL‐68(In)‐NH₂ on the Membrane Test Bench for Dye Removal and Carbon Capture

Abstract

Dedicated to Prof. Dr. rer. nat. Ju ¨rgen Caro on the occasion of his 70th birthdayThe metal-organic framework (MOF) MIL-68(In)-NH 2 was tested for dye removal from wastewater and carbon capture gas separation. MIL-68(In)-NH 2 was synthesized as a neat, supported MOF thin film membrane and as spherical particles using pyridine as a modulator to shape the morphology. The neat MIL-68(In)-NH 2 membranes were employed for dye removal in cross-flow geometry, demonstrating strong molecular sieving. MIL-68(In)-NH 2 particles were used for electrospinning of poylethersulfone mixed-matrix membranes, applied in dead-end filtration with unprecedented adsorption values. Additionally, the neat MOF membranes were used for H 2 /CO 2 and CO 2 /CH 4 separation.

Design of a Double-Photoelectrode Sensing System with a Metal–Organic Framework-Based Antenna-like Strategy for Highly Sensitive Detection of PD-L1

“…Based on the calculation of Hosseini Monjezi et al., the electron transfer path of MIL-68­(In)–NH 2 may be from the organic ligand to the metal cluster center, which is consistent with the ligand-to-metal charge transition (LMCT) reported in the literature . Therefore, we proposed the mechanism of photocathode MIL-68­(In)–NH 2 promoting charge separation, as shown in Figure B.…”

“…Based on this, the electrons flow to the photocathode through an external circuit, and the holes in the MIL-68(In)−NH 2 valence band consume part of the charge in a timely and effective manner, which promotes the continuous generation and migration of photogenerated carriers and enhances the response of the entire photocurrent system. Based on the calculation of Hosseini Monjezi et al, 31 the electron transfer path of MIL-68(In)−NH 2 may be from the organic ligand to the metal cluster center, which is consistent with the ligand-to-metal charge transition (LMCT) reported in the literature. 32 Therefore, we proposed the mechanism of photocathode MIL-68(In)−NH 2 promoting charge separation, as shown in Figure 3B.…”

Low‐Temperature Melting and Glass Formation of the Zeolitic Imidazolate Frameworks ZIF‐62 and ZIF‐76 through Ionic Liquid Incorporation

“…The procedure for MIL‐68(In) was adapted from the literature with small changes. [ 33 ] For the synthesis, 1.2377 g of In(NO 3 ) 3 ∙ x H 2 O and 0.2297 g terephthalic acid were dissolved in 13.28 ml DMF under stirring for about 15 min. The solution was transferred into a Teflon‐lined autoclave, sealed, and kept at 125 °C for 5h.…”

Preferential orientation of anisotropic polythiophene rods toward macroscopic chain ordering

“…, heating time and capping additive). 40–42 The anisotropic rod-shaped PTh particles with a controlled length was obtained using 1 as a template, in which the polymer chains were aligned along the long axis of the rods (Fig. 1).…”

“…In this study, [In(OH)(BDC-Br)] n (1; BDC-Br = 2-bromo-1,4benzenedicarboxylate, hexagonal channel size = 16 Å) was prepared, because the length of the host crystals can be tuned by the optimization of the synthetic conditions (e.g., heating time and capping additive). [40][41][42] The anisotropic rodshaped PTh particles with a controlled length was obtained using 1 as a template, in which the polymer chains were aligned along the long axis of the rods (Fig. 1).…”
