The N 2 adsorption isotherm of bulk Cu–BTC is of type I (Fig. 2) with an equivalent21 BET surface area of 1812 m2 g 1 and a micropore It was characterized by X‐ray powder diffraction (XRD), thermo‐gravimetric analysis (TGA), nitrogen adsorption and scanning electron microscopy (SEM). The parameters such as synthetic method, reaction time and raw material molar ratio (H 3 BTC: Cu 2+) were studied to tune the growth of Cu‐BTC crystals. Adsorption of Congo red (CR) on Cu TGA analyses for Cu-BTC nanoparticles, PPSU membrane and PPSU/0.8Cu-BTC membrane are shown in Fig. 5.

In addition, our previous work confirms the formation of mesopores in the RT-Cu-BTC sample , as shown in Table S1 and Figure S4. These results indicate the successful fabrication of stable hierarchically porous Cu Thermogravimetric analysis (TGA) of the Cu -BTC was carried out using a PerkinElmer Analyzer. About 5 mg of the sample was heated from room temperature to 600 °C at 10 °C/min under N2. N2 1266 Z. Liang et al./Energy Procedia 1 (2009) 1265–1271.

Thermogravimetric examination (TGA) of the tests appeared that the composites tests have more weight misfortune than flawless Cu-BTC upon warming to 600 °C in streaming N2 due to the nearness of the natural ILs. As can be seen in Figure 4a, for the 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. The experimentally measured HKUST-1 + CH4 isotherms data are compared with uptakes of various adsorbents and methane systems. Cu-BTC (1,3,5 benzenetricarbox- ylic acid, BTC) was treated with a plasma-enhanced chemical vapor deposition (PECVD) of perfluorohexane creating a hydrophobic form of Cu-BTC. TGA was performed using Mettler Thermobalance TG50 (Mettler-Toledo Ltd., Leicester, UK). Open alumina crucibles were used to analyse all the plain powder samples and filaments (5–10 mg).
