The purpose of this study is to simultaneously reduce NO_X and CO harmful gases according to the promoters and support types of the H₂-SCR. The 0.5Pt-2CeO₂-5Ru/TiO₂ catalyst loaded with 7 wt% Ru showed a lower NO_X conversion rate compared to than the 0.5Pt-2CeO₂/TiO₂ (STD), but the window shifted to the right, and it showed NO_X reduction performance of up to 30% at 175 °C. When Zr was loaded, de- NO_X performance was not improved at the temperature of 200 °C starting from a low catalyst temperature of 75 °C. With in the influence of the support types, the 0.5Pt-2CeO₂/TiO₂ H₂-SCR catalyst showed the highest NO_X conversion rate below 125 °C, and the low-temperature activity of NO_X was higher than that of the three zeolite-loaded H₂-SCR catalysts. Low temperature activity was improved because the TiO₂ has excellent reducing and oxidizing ability. Among the three zeolites, the CO reduction performance of the 0.5Pt-2CeO₂/Zeolite (1) catalyst with high Al content was the lowest.

本研究的目的是根据H _{2 -SCR的促进剂和载体类型同时减少NO X}和CO有害气体。负载7wt％Ru的0.5Pt-2CeO ₂ -5Ru/TiO _{2催化剂与0.5Pt-2CeO 2} /TiO ₂ (STD)相比表现出较低的NO _X转化率，但窗口向右移动，并且它在 175 °C 时表现出高达 30% 的NO _{X还原性能。}当负载Zr时，从75℃的低催化剂温度开始，在200℃的温度下，脱NO _{X性能没有得到改善。}受载体类型的影响，0.5Pt-2CeO ₂ /TiO ₂ H ₂ -SCR催化剂在125℃以下表现出最高的NO _{X转化率，且NO X}的低温活性高于载体。三种负载沸石的H ₂ -SCR催化剂。_{由于TiO 2}具有优异的还原和氧化能力，因此提高了低温活性。三种沸石中，高Al含量的0.5Pt-2CeO ₂ /Zeolite(1)催化剂的CO还原性能最低。
