초록
본 연구에서는 메조기공 탄소(CMK-3)를 KOH로 활성화 하여 실내공기 오염물질인 포름알데히드 흡착에 사용하였다. 활성화는 KOH 처리한 CMK-3를 700 ℃의 반응기에서 질소분위기로 수행하였다. 활성화된 시료의 특성은 BET, XRD, XPS, FT.IR을 통해 분석하였다. 포름알데히드의 흡착능은 활성화에 의해 향상되었으며, 이는 활성화에 의해 메조기공탄소의 산소작용기와 질소 작용기의 생성에 기인하는 것으로 판단된다.
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 °C in N2 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.
