“…These voids, that are much larger than solute size, may negatively affect membrane rejection rate. [23][24][25] Since the size, shape and chemical functionalities of the MOF cavities can be easily adjusted by choosing appropriate linker-metal couples, MMMs incorporated with MOFs have been widely used in gas separation processes. MOF is a porous crystalline material constructed from metal ions/clusters and multidentate organic linkers.…”

“…To emphasize the advantages of using Cu/MOF-74 as catalyst for the hydroacylation of phenylacetylene with ethyl glyoxalate to form (E)-ethyl 2-oxo-4-phenylbut-3-enoate, the catalytic activity of Cu/MOF-74 was comparedw ith that of other MOFs including Cu 2 (BDC) 2 (DABCO), Cu 3 (BTC) 2 ,C u(BDC), Cu 2 (NDC) 2 (DABCO), Cu 4 I 4 (DABCO) 2 ,N i-MOF-74, Zn-MOF-74, Fe 3 O(BDC) 3 ,I n(OH)(BDC), and Zr 6 O 4 (OH) 4 (BDC) 6 .T hese MOFs were synthesized by means of as olvothermal method, and characterized according to literature procedures. [69,70,[73][74][75][76][77] The hydroacylation reaction was carriedo ut in toluene at 100 8C under argon for four hours, using two equivalentso fe thyl glyoxalate, at ap henylacetylenec oncentration of 0.5 m,w ith 0.5 equivalent of morpholine as the base, in the presence of 10 mol %c atalyst. Ni-MOF-74, Zn-MOF-74, Fe 3 O(BDC) 3…”

“…Especially, the band at 1093 cm −1 is attributed to C─O─Cu stretching. The zone between 1,300 and 1,700 cm −1 is related to the carboxylate ligands and is thus indicative of the coordination of trimesic acid (BTC) with copper . The FTIR features observed at 1645 cm −1 corresponds to the asymmetric stretching of the carboxylate group of Cu‐BTC.…”
