Composite oxides: The NO conversion rate of a three-dimensionally ordered mesoporous (3DOM) Ce_0.8Cu_0.1Zr_0.1O₂ catalyst at lower temperature (150 °C) is close to 50 %. The catalyst exhibited remarkable resistance to H₂O and SO₂ poisoning, both individually and simultaneously. The formation of the 3DOM structure improves the reduction performance and surface active sites of the catalyst. In addition, the reaction of NO and CO over 3DOM Cu-CZ catalyst follows Langmuir-Hinshelwood and Eley-Rideal mechanism, respectively.

3DOM Ce0.8M0.1Zr0.1O2 (M=Cr, Sn, Fe, Co, Ni, Mn, Cu)催化剂在CO选择性催化还原NO中的活性测试及机理研究**

复合氧化物：三维有序介孔（3DOM）Ce _0.8 Cu _0.1 Zr _0.1 O ₂催化剂在较低温度（150°C）下的NO转化率接近50%。该催化剂对 H ₂ O 和 SO ₂中毒表现出显着的耐受性，无论是单独的还是同时的。3DOM 结构的形成提高了催化剂的还原性能和表面活性位点。此外，NO和CO在3DOM Cu-CZ催化剂上的反应分别遵循Langmuir-Hinshelwood和Eley-Rideal机制。
