一种大孔Ce‑Zr基复合金属氧化物催化剂及其制备方法和用途
摘要：
本发明提供一种大孔Ce‑Zr基复合金属氧化物催化剂及其制备方法和用途，所述复合氧化物催化剂为Ce‑X‑Zr复合氧化物，组成为：Ce0.8X0.1Zr0.1O2，X＝Fe,Mn,Co,Ni。其制备过程是将铁源、锰源、钴源、镍源中的一种通过原位掺杂溶于铈源、锆源中,采用碳模板支撑法合成。该催化剂能够将PM催化燃烧为CO2和催化还原NO为N2的温度降低到同一个范围内，同时提高催化PM燃烧的和NO的转化率活性；并且该催化剂制备方法简单，制备周期短，成本低，适用于柴油车尾气中PM和NO的去除，应用前景好。
摘要（英）：

The invention provides a macroporous Ce-Zr based composite metal oxide catalyst, a preparation method, and an application thereof. The composite metal oxide catalyst is a Ce-X-Zr composite oxide and has the constitution of Ce0.8X0.1Zr0.1O2, wherein X is Fe, Mn, Co or Ni. The preparation method includes the steps of in-situ-doping and dissolving one of an iron source, a manganese source, a cobalt source and a nickel source in a cerium source and a zirconium source, and performing carbon template supporting process to synthesize the composite metal oxide. The catalyst can reduce the temperatures of catalytic combustion of PM into CO2 and catalytic reduction of NO into N2 into the same range, and also is improved in activities of catalyzing the PM combustion and NO conversion rate. The preparation method is simple and has short period and low cost. The catalyst is suitable for PM and NO removal in tail gas of diesel vehicles and has excellent application prospect.
