“…22, such electrospun fibers exhibited a high CO adsorption rate. Furthermore, the CO adsorption rate was studied in various researches such as metal organic framework [71], zeolite [30] and activated carbon samples [72], and nanofibers have been used as new candidates in recent years. As can be observed, the PVA/Cs-CNs exhibited even higher adsorption potential in comparison.…”

“…Preparation of MIL-100(Fe): MIL-100(Fe) was prepared by a hydrothermal synthesis according to previous protocols in the literature. [16,27] Briefly, 0.56 g Fe, 1.41 g 1,3,5-BTC, 0.69 mL aqueous HF solution (50 %), 0.46 mL aqueous HNO 3 (60 %) and 50 mL ultrapure water were transformed into a 100 mL Teflon-lined stainless steel autoclave. The reaction mixture was stirred at room temperature for 30 min, and then the solution was heated up to 160°C for 12 h. The resulting orange solid was filtered and washed with hot water (80°C) and hot ethanol (60°C) until no colored impurities were detected in the mother liquor solution.…”

MIL‐100(Fe), a metal−organic framework containing coordinatively unsaturated iron sites, was prepared by a solvothermal method and utilized in cyclohexane oxidation. Interestingly, the composition and fraction of redox‐active Fe(II/III) sites in MIL‐100(Fe) could be tuned by using different pretreatment temperatures. The obtained materials were characterized by means of field‐emission scanning electron microscopy (FE‐SEM), powder X‐ray diffraction (PXRD), N2 adsorption‐desorption isotherms, and X‐ray photoelectron spectroscopy (XPS). Due to the presence of redox‐active coordinatively unsaturated sites (CUS) at the iron atoms, MIL‐100(Fe) exhibited good performance for cyclohexane oxidation under mild reaction conditions. Oxidation rates were significantly enhanced when reduced FeII sites were generated by high‐temperature pretreatments. In either high‐temperature or low‐temperature pretreatment, the isolated Fe(II/III) sites in MIL‐100 were far more reactive in cyclohexane oxidation than were bulk iron oxide materials. Finally, possible reaction pathways were proposed based on radical, Haber‐Weiss routes.

“…Working capacity is a standard critical parameter for evaluating the adsorbents in practical industrial applications. It is defined as the difference between the adsorbed amounts at adsorption and desorption conditions [29]. From pure CO 2 isotherm, the CO 2 working capacities between 100 and 10 kPa for LSX/AC-zeolite were calculated.…”

The porous carbonaceous precursor obtained from elutrilithe by adding pitch powder and solid SiO2 was employed for the first time in an in situ hydrothermal synthesis of LSX zeolite/AC composite. The synthesized samples were characterized by XRD, SEM, and N2 adsorption–desorption. The optimum conditions for the hydrothermal synthesis process were set as follows: gelling, aging, and crystallization. The time and temperature required for these steps were 24 h and 65 °C, 12 h and 20 °C, and 48 h and 65 °C, respectively. The molar ratios were (Na2O + K2O)/Al3O2 = 7.7, K2O/(K2O + Na2O) = 3. The potential applicability test of the product showed high CO2 working capacity, excellent CO2/CH4 and CO2/N2 selectivity, and high phenol adsorption capacity. These results suggest that the resultant product has excellent potential value in industrial application.
