In this work, ion exchange resin-based nanoporous carbons (MPCs) were prepared by MgO-templating synthesis and activated by KOH. MPCs were prepared from a (styrene-divinylbenzene)-based ion exchange resin by the carbonization of a mixture with Mg gluconate. And then, the prepared MPCs were treated with KOH at KOH/MPCs ratios ranging from 0.5 to 4. The textural properties of MPCs were investigated by N2/77 K full isotherms, SEM, and TEM. The CO2 adsorption capacity was measured by CO2 isothermal adsorption at 298 K and 30 bar. The prepared MPCs with a KOH/MPCs ratio=3 exhibited the best CO2 adsorption value of 1,385 mg/g at 30 bar. This result indicated that the CO2 adsorption capacity of MPCs attributed to the mesopore volume fraction at higher pressure. |
