Abstract
In this study, a mesoporous carbon (CMK-3) activated using KOH was applied to the adsorption of formaldehyde, a representative indoor air pollutant. Activation process was carried out by putting KOH-treated CMK-3 in a reactor maintained at $700^{\circ}C$ in $N_2$ atmosphere. The activated sample was characterized using BET, XRD, XPS and FT-IR analysis. The formaldehyde adsorption performance of the mesoporous carbon was improved, which is attributed to the formation of oxygen and nitrogen functional groups on the mesoporous carbon surface by the activation process.
