| 摘 要： | 采用浸渍法制备了 MnOx/Al0.82Ti0.18Ox (Mn/Al-Ti), Cu/Al-Ti, CuMn2/Al-Ti 和 CuMn2Zr1.25/Al-Ti 四种整体式催化剂, 并利用 X 射线衍射、X 射线光电子能谱、H2程序升温还原和氮吸附等手段对催化剂进行了表征, 考察了各整体式催化剂催化苯燃烧反应性能. 结果表明, ZrO2 的添加能明显提高催化剂的比表面积, 促进各活性组分的分散和表面氧浓度的增加, 从而提高催化剂表面的氧化能力, CuMn2Zr1.25/Al-Ti 整体式催化剂在 281 oC 时苯转化率达 91%, 表现出最高的低温催化活性.

| Abstract: | A series of MnOx/Al0.82Ti0.18Ox (Mn/Al-Ti), Cu/Al-Ti, CuMn2/Al-Ti, and CuMn2Zr1.25/Al-Ti monolithic catalysts were prepared by the wet impregnation method. X-ray diffraction, X-ray photoelectron spectroscopy, H2 temperature-programmed reduction, and N2 adsorption were used to characterize the catalysts. The results showed that the addition of ZrO2 in the catalysts increases the specific surface area, component dispersion, oxygen species concentration on the surface, and the redox ability of the catalysts. The monolithic catalysts have high catalytic activity, and the benzene conversion of 91% was obtained at temperature as low as 281 oC. |
