Abstract

In this study, we investigated the noble metal catalysts for HCHO removal at room temperature. These catalysts were characterized by XRD, FT-IR, CO-chemisorption. As a result, Pt and Pd based catalysts prepared by the reduction treatment showed the superior HCHO oxidation ability at room temperature. When the catalysts were prepared using $TiO_2$ support, which is well known as the reducing support, showed the superior activity. Also, the activity decreased by the agglomeration of active metal with increasing the reduction time. In case of reduction catalysts, it has been confirmed that the desorption and adsorption ability properties of HCHO is excellent at room temperature.

본 연구에서는, HCHO를 상온에서 제거하기 위한 귀금속계열의 촉매 연구를 수행하였다. 제조된 촉매들은 XRD, FT-IR, CO-chemisorption을 이용하여 특성분석을 수행하였다. 그 결과, Pt와 Pd를 활성금속으로 하여 제조한 환원촉매가 상온조건에서 우수한 HCHO 산화 능력을 보였으며, 지지체의 경우 환원성지지체로 잘 알려진 $TiO_2$를 이용하여 촉매를 제조하였을 때 높은 반응활성을 나타냈다. 또한, 환원시간이 길어짐에 따라 활성금속의 응집현상으로 인해 반응활성의 저하를 나타내었으며 환원촉매의 경우 상온조건에서 HCHO 흡착 및 탈착 특성이 우수함을 확인하였다.
