摘要/Abstract

摘要：

与汽油发动机相比, 柴油发动机具有热效率高、CO₂排放低、寿命长、续航距离远和经济性好等优点, 可大大缓解能源短缺, 降低 CO₂排放量. 因此, 机动车柴油化是当前发展趋势. 然而, 柴油发动机在使用过程中会排放大量炭烟颗粒物, 对人体危害极大. 因此, 控制炭烟颗粒排放成为环境催化研究的重点之一.
炭烟颗粒物催化燃烧反应是典型的固 (炭烟颗粒)-固 (催化剂)-气 (O₂) 多相催化反应. 三维有序大孔氧化物 (3DOM) 具有大孔径和内部贯通的孔道结构, 能有效提高炭烟颗粒与催化活性中心的接触性能. 同时, 纳米 Au 颗粒在大孔氧化物表面的负载可有效提高催化剂本征活性, 但纳米 Au 颗粒催化剂热稳定性较差. CeO₂具有较好的储放氧性能, 可与贵金属活性组分发生相互作用, 从而提高贵金属纳米颗粒的分散度和稳定性. 因此, 本文从柴油炭烟颗粒物催化燃烧反应本质出发, 设计制备了高炭烟燃烧催化活性的 3DOM 氧化物担载 Au 基催化剂, 研究了 Au 与 CeO₂强相互作用对炭烟燃烧活性的影响.
采用胶体晶体模板法制备 3DOM Al₂O₃载体, 由微孔膜氨沉淀法制备 CeO₂/3DOM Al₂O₃催化剂, 以还原-沉积法制备 Au/3DOM Al₂O₃和 Au/CeO₂/3DOM Al₂O₃催化剂, 并利用扫描电镜、N₂物理吸附-脱附、X 射线衍射、透射电镜、紫外漫反射光谱、H₂程序升温还原和 X 射线光电子能谱等手段对催化剂形貌、比表面积、物理化学性质和氧化还原性进行了表征. 结果表明, 在 CeO₂/3DOM Al₂O₃中, Al³⁺可进入到氧化铈晶格内, 形成 Al-Ce-O 固溶体, 产生氧空位, 这有利于氧物种转移. 此外, Au/CeO₂/3DOM Al₂O₃催化剂中 Au 和 CeO₂ 之间的强相互作用能增加 Au 纳米颗粒表面活性氧物种数量, 从而促进柴油炭烟燃烧反应. 纳米颗粒 Au 的担载使得催化柴油炭烟燃烧的起燃温度明显降低, 其中 Au/CeO₂/3DOM Al₂O₃催化剂表现出最高的催化活性, T₁₀, T₅₀和 T₉₀分别为 273, 364 和 412 ^oC.

Abstract:

Au/3DOM (three-dimensionally ordered macroporous) Al₂O₃ and Au/CeO₂/3DOM Al₂O₃ were prepared using a reduction-deposition method and characterized using scanning electron microscopy, N₂ adsorption-desorption, X-ray diffraction, transmission electron microscopy, ultraviolet-visible spectroscopy, temperature-programmed hydrogen reduction, and X-ray photoelectron spectroscopy. Au nanoparticles of similar sizes were well dispersed and supported on the inner walls of uniform macropores. The norminal Au loading is 2%. Al-Ce-O solid solution in CeO₂/3DOM Al₂O₃ catalysts can be formed due to the incorporation of Al³⁺ ions into the ceria lattice, which causes the creation of extrinsic oxygen vacancies. The extrinsic oxygen vacancies improved the oxygen-transport properties. The strong metal-support interactions between Au and CeO₂ increased the amount of active oxygen on the Au nanoparticle surfaces, and this promoted soot oxidation. The activities of the Au-based catalysts were higher than those of the supports (Al₂O₃ or CeO₂/3DOM Al₂O₃) at low temperature. Au/CeO₂/3DOM Al₂O₃ had the highest catalytic activity for soot combustion, with T₁₀, T₅₀, and T₉₀ values of 273, 364, and 412 ℃, respectively.
