Abstract

We synthesized four CeO-MnO mixed oxides with different morphologies using simple hydrothermal methods. The catalytic activity for chlorobenzene (CB) degradation decreases in the following order: rod-CeO-MnO > plate-CeO-MnO > polyhedra-CeO-MnO > cube-CeO-MnO . CeO and MnO in the mixed oxides are highly dispersed and two new phases of both todorokite (S.G.: 2/:) and vernadite (S.G.: 4/) with a special tunnel-like structure are found. Both rod-CeO-MnO and plate-CeO-MnO exhibit increased lattice microstrains generated from lattice distortion and defects; further, there are more oxygen vacancies and more MnO (Mn and Mn) species on the surface, particularly when compared to cube-CeO-MnO . Therefore, this promotes deeper oxidation activity for CB. Moreover, the strong interaction between CeO and MnO also promotes the redox ability of CeO-MnO mixed oxides, while their oxygen storage capacity (OSC) properties are not only intrinsic to their structures but also limited to their surfaces and by their particle sizes.

摘要

我们采用简单的水热法合成了四种不同形貌的CeO-MnO混合氧化物。对氯苯（CB）降解的催化活性按以下顺序降低：棒状CeO-MnO＞片状CeO-MnO＞多面体CeO-MnO＞立方状CeO-MnO。混合氧化物中的CeO和MnO高度分散，发现了具有特殊隧道状结构的钙锰矿（空间群：2/:）和水钠锰矿（空间群：4/）这两个新相。棒状CeO-MnO和片状CeO-MnO均表现出由晶格畸变和缺陷产生的晶格微应变增加；此外，与立方状CeO-MnO相比，其表面有更多的氧空位和更多的MnO（Mn和Mn）物种。因此，这促进了对CB的深度氧化活性。此外，CeO和MnO之间的强相互作用也促进了CeO-MnO混合氧化物的氧化还原能力，而它们的储氧能力（OSC）特性不仅取决于其结构，还受限于其表面和粒径。
