초록

본 연구에서는, Ru[1]/TiO2 촉매 제조 시 소성/환원 조건에 따른 NH3-SCO (selective catalytic oxidation) 효율을 비교하였다. Ru[1]/TiO2 red는 Ru[1]/TiO2 cal에 비하여 NH3 전환율 및 NH3의 N2 전환율이 우수하였다. Ru[1]/TiO2 촉매의 물리. 화학적 특성은 BET, XRD, TEM, XPS, H2-TPR 분석에 의해 확인되었으며, 활성금속의 분산도와 표면 흡착 산소종(Oβ)의 비율에 영향을 미치는 것으로 나타났다.

In this study, NH3-selective catalytic oxidation (SCO) efficiencies according to calcination/reduction conditions were compared when preparing various Ru[1]/TiO2 catalysts. The Ru[1]/TiO2 red catalyst had better NH3 conversion and NH3 to N2 conversion than those of Ru[1]/TiO2 cal. Physico-chemical properties of Ru[1]/TiO2 catalysts were confirmed by Brunauer Emmett Teller (BET), X-ray diffraction (XRD), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and temperature programmed reduction (H2-TPR) analyses, and the properties were shown to affect the dispersion and surface adsorption oxygen species (Oβ) ratio of the active metal.
