Abstract

Carbon dioxide (CO₂) capture has emerged as a critical strategy for mitigating greenhouse gas emissions and addressing global climate change. In this study, a series of MgO-supported activated carbon adsorbents containing 2, 4, 6, 8, and 10 wt% MgO were successfully synthesized using the impregnation method to evaluate their CO₂ adsorption performance. The structural, chemical, and surface properties of the prepared materials were characterized using powder X-ray diffraction (PXRD), Fourier-transform infrared (FT-IR) spectroscopy, nitrogen (N₂) adsorption–desorption isotherms, and elemental analysis. CO₂ adsorption experiments were conducted in a fixed-bed reactor under ambient conditions at atmospheric pressure and 30 °C to assess the adsorption capacities of the synthesized adsorbents. Among the prepared samples, the adsorbent containing 8 wt% MgO exhibited the highest CO₂ adsorption capacity of 125 μmol/g, outperforming the other MgO loadings due to its optimal dispersion of active MgO sites and favorable pore structure. In addition to its high adsorption efficiency, the 8 wt% MgO-supported activated carbon demonstrated excellent cyclic stability, maintaining its adsorption capacity over 10 consecutive adsorption–desorption cycles without any noticeable loss in performance. These results indicate that an appropriate MgO loading significantly enhances the CO₂ capture ability of activated carbon while preserving its structural integrity and reusability. The findings highlight the potential of 8 wt% MgO-supported activated carbon as a cost-effective, efficient, and durable adsorbent for practical carbon capture applications in industrial gas purification and environmental protection.
