초록

본 연구에서는, 다양한 오염원에서 발생되는 암모니아를 제어하기 위해 $Ce/TiO_2$ 촉매를 이용한 암모니아의 선택적 촉매 산화반응에 관한 연구가 수행되었다. Ce 함량이 10 wt%가 될 때까지는 Ce 함량이 증가할수록 촉매 성능이 증진됨이 관찰되었다. 그러나 그 이상의 함량에서는 오히려 촉매활성이 감소하였다. 따라서 본 연구에 의한 최적 $Ce/TiO_2$ 촉매는 실제 현장에 적용될 수 있을 것으로 판단된다.

In this study, selective catalytic oxidation (SCO) of $NH_3$ using $Ce/TiO_2$ catalyst was examined to control the slipped NH3 from various pollutants. It was found that the catalytic activity increased with increasing the Ce loadings till reaching 10 wt% Ce loading. However, when Ce loaded over 10 wt%, the activity of catalysts rather decreased than that of catalysts, below 10 wt% Ce. Therefore, the composition of $Ce/TiO_2$ catalyst optimized in this study can be applied to industrial fields.
