A zeolite sheet (ceramic paper containing zeolite) made in a cylindrical configuration can be applied to a honeycomb rotor for the effective VOC removal. In this study, the zeolite sheet containing ZSM-5 was used as a support for Pt-loading, and its catalytic activity for the toluene combustion reaction was compared with those of the other Pt catalysts loaded on γ-Al2O3 and cordierite honeycomb. Pt/zeolite sheet catalyst showed a higher activity for toluene combustion reaction than that of Pt/γ- Al2O3 or Pt/cordierite honeycomb. On the other hand, the dispersion of Pt particles loaded on the zeolite sheet was improved by the pretreatment with NH3-H2O vapor at room temperature. Consequently, the pretreatment of Pt/zeolite sheet by NH3-H2O vapor significantly enhanced the catalytic activation for toluene combustion reaction.

원통형으로 성형된 zeolite sheet (제올라이트를 함유하는 세라믹 종이)는 VOC 제거를 위한 효과적인 흡착로터로서 사용될 수 있다. 본 연구에서는 ZSM-5가 함유된 zeolite sheet 지지체에 Pt를 담지한 후 톨루엔 연소 촉매 성능을 γ-Al2O3 및 cordierite honeycomb 지지체에 담지된 Pt 촉매와 비교하였다. Pt/zeolite sheet 촉매는 Pt/γ-Al2O3 또는 Pt/cordierite honeycomb 촉매에 비하여 톨루엔 연소반응에 높은 활성을 나타냈다. 한편, Pt/zeolite sheet 촉매를 상온에서 NH3-H2O 증기로 전처리하면 zeolite sheet에 담지된 Pt 입자의 분산도가 향상되었으며, 톨루엔 연소 촉매 활성이 크게 증가하였다.
