초록
본 연구는 대기 중 대표적인 미세먼지 2차 유발물질인 질소산화물 제어에 있어 암모니아를 환원제로 사용하는 선택적촉매 환원법(Selective Catalytic Reduction; SCR)을 이용한 연구를 수행하였다. NH3-SCR 실험은 상용촉매인 V/W/TiO2와 Sb를 첨가한 V/W-Sb/TiO2 촉매를 사용하였으며 phosphorous에 의한 내피독성을 확인하였다. NH3-SCR 실험 결과, Sb의 첨가는 P에 대한 내구성을 갖는 것으로 확인되었다. 또한 이에 대한 원인을 확인하기 위하여 BET, XPS, H2-TPR, NH3-TPD, FT-IR 분석을 통해 물리·화학적 특성을 비교분석하였다. 분석 결과 V/W/TiO2 촉매에 Sb 첨가 시 P가 첨가됨에 따라 SbPO4 결합을 형성하고 VOPO4의 생성을 억제하였으며, P 첨가 전 촉매의 redox 특성을 유지함으로써 P에 대한 내피독성을 확인하였다.
A study using selective catalytic reduction (SCR) was conducted in conjunction with ammonia as a reducing agent for controlling nitrogen oxides, a typical secondary inducer of fine dust in the atmosphere. For NH3-SCR experiments, a commercial catalyst of V/W/TiO2 only and also V/W-Sb/TiO2 catalyst with Sb were used, and phosphorous durability was confirmed. As a result of NH3-SCR experiments, it was confirmed that the addition of Sb to V/W/TiO2 had durability against phosphorous. In addition, the physical and chemical properties were comparatively analyzed through BET, XPS, H2-TPR, NH3-TPD, and FT-IR analysis. From the anaylsis results, when Sb was added to V/W/TiO2 catalyst, P was also added resulting in the formation of SbPO4 and the generation of VOPO4 was suppressed. The phosphorous durability was confirmed by maintaining the redox characteristics of the catalyst before P was added.
