In this work, mesoporous carbons (CMK-3) were prepared by hard-templating method using SBA-15 for CO2 adsorption. And further, the CMK-3 was chemically activated to obtain high specific surface area and micropore volume with different KOH amounts (i.e., 0, 1, 3, and 4) as an activating agent. The characteristics of the samples were investigated by N2/77 K adsorption isotherms, X-ray diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscopy (TEM). The CO2 adsorption performance was measured by CO2 isothermal adsorption. From the results, the CMK-3 activated with KOH showed that the increasing specific surface areas and total pore volumes, resulted in the enhancement of CO2 adsorption capacity. |
