Amino-functionalized Zr-MOF nanoparticles for adsorption of CO2and CH4

Abstract: Amino-functionalized Zr-MOF (amino-Zr-MOF) was synthesized using 2-aminoterephthalic acid as an organic linker. The physicochemical properties of the material were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and N 2 adsorption to understand its crystalline structure, morphology, thermal stability, and porous structure. CO 2 adsorption isotherms on amino-Zr-MOF were obtained at 1 atm and at differ… Show more

“…The adsorption capacity of the sludge is comparable with activated UiO-66 [58]. However, the adsorption capacity of sludge is lower than that of DAAB and Zr-MOF [1,26].…”

“…In addition, adsorption on solid adsorbent is a promising alternative method due to the potential of handling higher throughput for regeneration [18]. Adsorbents such as zeolites [19][20][21][22], siliceous compounds [19,23], metal-organic frameworks [24][25][26], hydrotalcites [27,28], activated carbons [29,30] and metal oxides [27] have been…”

“…The loss of 10% weight at approximately 270°C was probably due to the volatilization of DMF in the pores that was not replaced by chloroform. The loss of 40% weight above 350°C was related to the decomposition of UiO‐66‐NH 2 into CO, CO 2 , and ZrO 2 . For Br@UiO‐66‐NH 2 , the decomposition temperature was reduced to approximately 200°C, which was due to the decomposition of bonded 2‐bromoisobutyryl bromide (the bonding extent was approximately 12.9%.…”

“…As shown in Figure 3, characteristic symmetrical and asymmetrical stretching vibration absorption peaks of -COO − appeared at 1385-1572 cm −1 in the three curves (Figure 3a,b, and c), indicating that UiO-66-NH 2 , Br@UiO-66-NH 2 and MIP@UiO-66-NH 2 had the same UiO-66-NH 2 core. The characteristic symmetrical and asymmetrical stretching vibration absorption peaks of N-H were present at 3351 and 3461 cm −1 in Figure 3a, which were shoulder peaks, forming the characteristic absorption band of primary amines [22][23][24]. In Figure 3b, the symmetrical and asymmetrical stretching vibration peaks of -C-H within -CH 3 and -CH 2 appeared between 2867 and 2975 cm −1 .…”
