“…The XRD structural patterns of the MIL-101(Cr) adsorber from 2θ to 80θ were consistent with those reported by previous researchers [57,58], and the XRD peaks con rmed the cubic structure [59]. All the diffraction peaks of the MIL-101(Cr) sample agreed with the calculated peaks, indicating the successful synthesis of the MIL-101(Cr) substance [60,61].Characteristic peaks at 2θ, 5.25, 5.88, 8.42, 9.06, and 16.50 were assigned to crystallographic planes [62].…”

Hydrogen sulfide gas is a challenge in the oil and gas industry due to its toxicity and corrosive nature. In addition to the toxicity of H2S, it is very corrosive both in gas and when dissolved. It is oxidized when oxidized in the combustion process, and the form of SO2 causes acid rain. Adsorption using MIL-101(Cr) @NIPs/MIPs@H2S adsorbents offers a promising solution with high efficiency, low cost, and low energy consumption. This study optimized the operating parameters for efficient and cost-effective adsorption of H2S gas. Thirty experiments were conducted to analyze the impact of the operating parameters of the adsorbent (0.1 to 1 g), temperature (25 to 80°C), concentration (10 to 1000 ppm), and flow rate (40 to 100 mL/min) on the process. The evaluation was carried out to determine cause-and-effect relationships between the variables above. The molar adsorption capacity of gases in a 400 mm high, 10 mm internal diameter fixed bed was determined using the central composite design method and the Soave-Redlich-Kwong equation. FTIR, XRD, FE-SEM, and BET techniques were then used to determine the physical properties. The statistical analysis of variance results indicated that the adsorbents adhere to the quadratic model, with temperature and adsorbent dose being the primary process variables. The optimum adsorption efficiency and capacity for MIL-101(Cr)@MIPs@H2S (11 mg/g = 94.3%) is higher than that of MIL-101(Cr)@NIPs@H2S (5.97 mg/g = 9.9%) and due to a better match between the template and binding sites in the template layer, which facilitates efficient template uptake and removal. The equilibrium adsorption of all Nano-adsorbents followed the pseudo-Scott order and Langmuir isotherm models. MIL-101(Cr) @MIPs@H2S proved to be a reliable and stable adsorbent for hydrogen sulfide. Its specific adsorption selectivity for H2S resulted in a significantly higher adsorption capacity than other gases in mixed CO2 and CH4.

“…However, the overall EDX analysis result for the MIL-101(Cr) synthesized in this work is in line with the changes in the Cr to BDC molar ratio used. The results of the FTIR analysis conducted on the MIL-101(Cr) in Figure 4 are in accordance with the literature data [16][17][18], particularly in the fingerprint region between 400 and 1500 cm −1 . An intense absorption band around 520 cm −1 occurred due to the chromium-to-oxygen stretching vibration [18].…”

“…When the molar ratio was decreased from 1.5:1 to 1:1, we observed fine growth of small, irregular, granular-shaped particles in an aggregation state (Figure 3d). The findings are similar to the MIL-101(Cr) morphology reported elsewhere [16,17], indicating that MIL-101(Cr) can grow well using the solvent-free method with an equal molar ratio of Cr to BDC organic linker. The surface of MIL-101(Cr) with 2:1 and 2.5:1 Cr to BDC molar ratio was found to have many regular round-shaped particles, as shown in Figure 3f,g, respectively.…”

“…The XRD patterns of the MIL-101(Cr) synthesized using the solvent-free method in Figure 2 are in agreement with those reported in the literature [16,17], confirming the successful formation of pure MIL-101(Cr). The diffraction peak became stronger as the Cr to BDC molar ratio increased.…”

“…Most of the absorption bands at the region between 600 and 1600 cm −1 belonged to the functional groups and the benzene ring within the BDC organic linker that participated in the formation of MIL-101(Cr) [18]. The strong peak at 720 cm −1 was attributed to the mono-substituted benzene ring [17], while the peak at 750 cm −1 was the vibration of the C-H group [18]. In addition, the peaks around 1390 and 1450 cm −1 were due to the symmetrical vibration of the O-C-O of the benzene ring and the dicarboxylate functional group, respectively, within the BDC [20].…”

MIL-101(Cr), a subclass of metal–organic frameworks (MOFs), is a promising adsorbent for carbon dioxide (CO2) removal due to its large pore volume and high surface area. Solvent-free synthesis of MIL-101(Cr) was employed in this work to offer a green alternative to the current approach of synthesizing MIL-101(Cr) using a hazardous solvent. Characterization techniques including XRD, SEM, and FTIR were employed to confirm the formation of pure MIL-101(Cr) synthesized using a solvent-free method. The thermogravimetric analysis revealed that MIL-101(Cr) shows high thermal stability up to 350 °C. Among the materials synthesized, MIL-101(Cr) at the molar ratio of chromium precursor to terephthalic organic acid of 1:1 possesses the highest surface area and greatest pore volume. Its BET surface area and total pore volume are 1110 m2/g and 0.5 cm3/g, respectively. Correspondingly, its CO2 adsorption capacity at room temperature is the highest (18.8 mmol/g), suggesting it is a superior adsorbent for CO2 removal. The textural properties significantly affect the CO2 adsorption capacity, in which large pore volume and high surface area are favorable for the adsorption mechanism.
