Co2 Adsorption Capacity

CO2 is a major contributor to global warming, and considerable efforts have been undertaken to capture and utilise it. Herein, a nanomaterial based on ionic liquid (IL)–modified calcined magnesites was investigated for CO2 capture. The synthesised nanomaterial (magnesite modified using [APMIM]Br) exhibited the best adsorption performance of 1.34 mmol/g at 30% IL loading amount, 50 °C, 0.4 MPa and 150 mL/min. In particular, the obtained nanomaterial could be regenerated at a low temperature of 90 °C for 3 h, and its CO2 adsorption capacity of 0.81 mmol/g was retained after eight cycles. FT-IR results showed that the imidazole ring and C–N group are directly related to CO2 adsorption capacity. Moreover, improving the conjugative effect of the imidazole ring enhanced the adsorption performance. Further, CO2 was adsorbed on the adsorbent surface and incomplete desorption decreased the BET surface area and CO2 adsorption capacity. Additionally, four models were selected to fit the adsorption kinetics. The results show that the adsorption mechanism fits the pseudo-first-order model well.

Abstract Adsorption functionalized poly(ionic liquid)s could be thiol-ene click synthesized within surfactant-free ionic liquid microemulsions. However, the influence of the mole fraction of pendant enes on the as-prepared polymer is still unclear. Herein, the influence of the mole fraction of pendant enes on the molecular structure, surface morphology, thermostability and adsorption performance of poly(ionic liquid)s were investigated in detail. To characterize the as-prepared polymers, FTIR, NMR, TGA, DSC, SEM and UV–vis were used, and the adsorption isotherm/kinetics studies were carried out. The results show that the mole fraction of pendant enes had a significant difference on the characterization of poly(ionic liquid)s. The lower mole fraction of pendant enes donated lower T10% value, slower degradation rates and lower Tg, and the value of 0.30 was the boundary of forming structure with various beading sizes and structure with various irregularly shaped apertures. In addition, poly(ionic liquid)s with different mole fraction of pendant enes all showed excellent adsorption performance to DR, also indicate remarkable potential in the application of dying wastewater treatment.
