一种同时消除NH3、NO和碳烟颗粒的复合氧化物催化剂及其制备方法和用途
摘要：
本发明提供了一种同时消除NH3、NO和碳烟颗粒的复合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铈钨钛复合氧化物或铈钼钛复合氧化物，所述铈钨钛复合氧化物具有如下组成：Ce1-x-dWxTidO2或Ce1-x-dMoxTidO2，其中，x＝0.005～0.1，d＝0.095～0.39。该复合氧化物催化剂能够将碳烟颗粒物燃烧为CO2的温度、NO和NH3转化的温度降低到同一个范围内，同时提高NO的转化率和碳烟催化燃烧的活性；该复合氧化物催化剂的制备方法简单，制备周期短，成本较低，适用于柴油车尾气中NOx和碳烟颗粒的去除，应用前景好。
摘要（英）：

The invention provides a composite oxide catalyst for eliminating NH3, NO and soot particles at the same time and a preparation method and purpose of the composite oxide catalyst. The composite oxide catalyst is cerium, tungsten and titanium composite oxide or cerium, molybdenum and titanium composite oxide. The cerium, tungsten and titanium composite oxide comprises Cel-x-dWxTidO2 or Cel-x-dMoxTidO2, wherein x ranges from 0.005 to 0.1, and d ranges from 0.095 to 0.39. The temperature of CO2 and the conversion temperature of NO and NH3 are lowered to the same range by combusting soot particles through the composite oxide catalyst, and meanwhile the conversion rate of NO and the activity of soot catalytic combustion are increased. The composite oxide catalyst is simple in preparation method, short in preparation period, low in cost, suitable for removing NOx and soot particles in tail gas of diesel vehicles, and good in application prospect.
