A Multi-Functional In(III)-Organic Framework for Acetylene Separation, Carbon Dioxide Utilization, and Antibiotic Detection in Water

Abstract

The reaction of In 3+ ions with 2,5-di(2H-tetrazol-5-yl) terephthalic acid (H 4 dtztp) affords a 3D indium-organic framework, [In(dtztp) 0.5 (OH)(H 2 O)]•H 2 O (1) with a (3,6)connected net. 1 shows good thermal (300 °C) and chemical stabilities (various organic solvents and acidic/basic solutions) and excellent water tolerance (7 days at room temperature or in boiling water). The acetylene (C 2 H 2 ) sorption behavior of 1 indicates significant separation selectivity over CH 4 , as confirmed by breakthrough experiments on the realistic gas mixtures. Meanwhile, the MOF with the Lewis and Brønsted acidic bifunctional catalytic sites catalyzes the CO 2 conversion with different epoxides with high yields. The fluorescent properties reveal the efficient probing performance of 1 for nitrofurantoin (NFT) and metronidazole (MDZ) in water with a low detection limit (ppm).

Electrostatic force-driven lattice water bridging to stabilize a partially charged indium MOF for efficient separation of C2H2/CO2 mixtures

“…FJU- 118 can survive in an wider pH range, compared with some In-MOFs, such as V102 (pH 4–9), 49 InOF-1 (pH 3–11) 50 and [In(dtztp) 0.5 (OH)(H 2 O)]·H 2 O (pH 3–11). 51 In contrast, the framework of FJU- 117 began to collapse shortly after the solvent was removed. The XPS spectra of the FJU- 117 , FJU- 118 and FJU- 118 a samples are shown in Fig.…”
