| 摘 要： | 采用固定床反应器评价了整体式催化剂 Pt/γ-Al2O3/Ce0.5-xZr0.5-xMn2xO2 去除饮食油烟的催化性能. 制备了一系列不同 Mn 含量的 Ce0.5-xZr0.5-xMn2xO2 储氧材料, 并考察了其作为载体对 Pt/γ-Al2O3/Ce0.5-xZr0.5-xMn2xO2 催化剂活性的影响. 应用 X 射线衍射 (XRD)、N2 物理吸附和 H2 程序升温还原 (H2-TPR) 等手段对催化剂进行了表征. XRD 结果表明, 贵金属 Pt 很好地分散在载体 γ-Al2O3 和 Ce0.5-xZr0.5-xMn2xO2 上. N2 物理吸附和 H2-TPR 研究结果与催化剂活性测试能很好吻合. 催化剂的活性顺序为 x = 0.10 > x = 0.15 > x = 0.05 > x = 0 > x = 0.20, Pt/γ-Al2O3/Ce0.4Zr0.4Mn0.2O2 催化剂活性最好, 油烟完全转化温度仅为 495 K.
