“…This may be related to the unsaturated metal sites of Cu 2 TPTC-Me is ~3.3 mmol g -1 and the C 2 H 2 adsorption initial Q st is about 19.1 kJ mol -1 , which both are lower than these MOFs with high acetylene storage capacity [46], resulting in adsorbing less acetylene at low pressure. The acetylene delivery capacity of Cu 2 TPTC-OMe reaches up to 143 cm 3 g -1 under the same conditions.…”

“…Recently, some MOF materials such as MOF-5 [23][24][25], MIL-125 [26], and MIL-53(M) (M = Fe, Al, and Cr) [27] have been applied successfully in the decolorization of various dyes in aqueous solutions. Owing to its excellent porosities (high specific surface area, large pore volume, and uniform pores), MIL-101 is a good candidate in catalysis [28] and has been found to be a great candidate for many other applications [16,17,[29][30][31][32]. Several papers have reported visible-light photocatalytic activity of modified MIL-101, e.g., N-K 2 Ti 4 O 9 /MIL-101 composite [33] and Bi 25 FeO 40 /MIL-101/PTH [34].…”

In the present paper, the synthesis of metal-organic framework MIL-101 and its application in the photocatalytic degradation of Remazol Black B (RBB) dye have been demonstrated. The obtained samples were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and nitrogen adsorption/desorption isotherms at 77 K. It was found that MIL-101 synthesized under optimal conditions exhibited high crystallinity and specific surface area (3360 m2·g-1). The obtained MIL-101 possessed high stability in water for 14 days and several solvents (benzene, ethanol, and water at boiling temperature). Its catalytic activities were evaluated by measuring the degradation of RBB in an aqueous solution under UV radiation. The findings show that MIL-101 was a heterogeneous photocatalyst in the degradation reaction of RBB. The mechanism of photocatalysis was considered to be achieved by the electron transfer from photoexcited organic ligands to metallic clusters in MIL-101. The kinetics of photocatalytic degradation reaction were analyzed by using the initial rate method and Langmuir-Hinshelwood model. The MIL-101 photocatalyst exhibited excellent catalytic recyclability and stability and can be a potential catalyst for the treatment of organic pollutants in aqueous solutions.

Acetylene separation is a very important but challenging industrial separation task. Here, through the solvothermal reaction of CuI and 5-triazole isophthalic acid in different solvents, two metal-organic frameworks (MOFs, FJU-21 and FJU-22) with open O donor sites and controllable robustness have been obtained for acetylene separation. They contain the same paddle-wheel {Cu2(COO2)4} nodes and metal-ligand connection modes, but with different helical chains as secondary building units (SBUs), leading to different structural robustness for the MOFs. FJU-21 and FJU-22 are the first examples in which the MOFs' robustness is controlled by adjusting the helical chain SBUs. Good robustness gives the activated FJU-22 a, which has higher surface area and gas uptakes than the flexible FJU-21 a. Importantly, FJU-22 a shows extraordinary separation of acetylene mixtures under ambient conditions. The separation capacity of FJU-22 a for 50:50 C2H2/CO2 mixtures is about twice that of the high-capacity HOF-3, and its actual separation selectivity for C2H2/C2H4 mixtures containing 1% acetylene is the highest among reported porous materials. Based on first-principles calculations, the extraordinary separation performance of C2H2 for FJU-22 a was attributed to hydrogen-bonding interactions between the C2H2 molecules with the open O donors on the wall, which provide better recognition ability for C2H2 than other functional sites, including open metal sites and amino groups.
