MOF, PLLA, PLLAe5% MOF, PLAe10% MOF and PLAe20% MOF was performed using a TGA 2950 (TA-Instruments, New Castle, DE, USA) under nitrogen ﬂow of 100 ml/min. Samples weighing between 5 and 10 mg were heated at a rate of 10. C/min from 25.

We have measured the methane uptakes on HKUST (Copper benzene-1,3,5-tricarboxylate, Cu-BTC MOF)-1 MOF (metal organic framework) for the temperatures ranging from 120 K to 300 K and pressures up to 10 bar. Cu-BTC nanoparticles were homogeneously dispersed in PPSU dope solution prior to the casting process, and their subsequent presence in the PPSU membrane was inferred by a combination of FTIR spectroscopy, TGA, SEM, EDX and AFM analyses. exception of TGA, as only the Cu-BTC-IL-5% samples were tested by this technique. Elemental analysis was performed on an elemental microanalyzer (CHNS) based on the complete and instantaneous oxidation of the sample in order to obtain the total amount of elements such as carbon, hydrogen, nitrogen and sulphur on modified Cu-BTC. The thermal stability of Cu/Co-BTC was detected using a thermogravimetric analysis (TGA) unit (STA-499C). The TGA curve of Cu-BTC-mmen almost remained that of Cu-BTC-raw but the weight loss increased, which could be attributed to the removal of N,N-dimethylethylenediamine. In Fig. 5 b, the weight loss of disposed with water vapor was almost equal to that of fresh sample.

For the MMMs with different Cu(BTC) loadings (10, 20, and 30% ( w/w )), the weight loss is more significant with increasing MOF content, however, the thermal decomposition temperature Both kinds of Cu-BTC were further characterized with thermogravimetric analysis (TGA) in N 2 gas, as shown in curve a and b in Fig. 1H. For six-prismatic crystals (curve b), it shows a loss of 17% due to coordinated water vapor at 220°C, roughly corresponding to three water molecules per formular unit. For the first time in this study compared the adsorption capacity and selectivity of carbon dioxide (CO 2), methane (CH 4), and nitrogen (N 2) on amine‐modified copper(II) benzene‐1,3,5‐tricarboxylate (Cu‐BTC) and metal organic framework‐derived nanoporous carbon (MOF/NPC) by employing a volumetric measurement.The MOF/NPC is synthesized via direct carbonization of the Cu‐BTC as a The Cu-BTC was prepared by the same method as the PVP/Cu-BTC except without addition of PVP.
