纳米级稀土材料在汽车尾气净化中的应用

Application of namometerial of rare earths for the purification of automobile exhaust gases

汽车尾气是当今大气污染的主要来源之一 ,催化净化是国际普遍采用的汽车尾气净化法。本文根据我国贵金属贫乏而稀土资源丰富的国情 ,以及稀土纳米材料特有的性质和功能 。

The automobile exhaust emission is one of the leading sources of the pollution of the atmosphere in present,and the catalyst purification is the popular means for the purification of automobile exhaust emission in the world.Depending on the case that there are scarce noble metals and functions of nanomaterial of rare earths,the application of nanomaterial of rare earths for the purification of automobile exhaust gases and its prospect are discussed.
