| 제목 | CO2 sorption of mesoporous magnesium oxides at ambient temperature |
| 초록 | Carbon dioxide (CO2) accumulates in the atmosphere and results in increase in the average global temperature and climatic changes. Therefore, CO2 capture has attracted the researcher’s attention to design potential sorbents recently. In this work, Mesoporous magnesium oxide (MgO) was synthesized by aero-gel method using magnesium methoxide as precursor, toluene as solvent and distilled water as reactant. Particle morphology was polyhedral sharp and aggregated in SEM images. The type-IV adsorption isotherm with H1 hysteresis obtained by N2 adsorption/desorption study for MgO. The performance of as-prepared mesoporous MgO toward CO2 was analyzed in thermograimetirc analysis (TGA). At room temperature (25oC), the CO2 sorption capacity was up to 10.6wt%. The sorption capacity decreased with an increase in CO2 temperature. Finally, the thermal stability of mesoporous MgO was tested by the cyclic test of CO2 sorption and regeneration in this work. |
