Au催化剂相对于Pt,Pd和Rh等贵金属催化剂具有更大储量且价格低廉,且Au催化剂具有较高的低温催化活性及催化活性随湿度增加而增加,因而在汽车排放净化应用方面,开始受到各国学者的关注。我们着重介绍Au纳米催化剂的研究历程、在内燃机排气净化方面的应用现状及Au纳米催化剂的制备方法。

Compared to the precious platinum group metals (PGM) including Pt, Pd and Rh, the Au catalyst has much more resources and lower price, and the Au catalyst has higher catalytic activity at low temperature even with the humidity increases, so the Au catalyst receives more and more attention of worldwide scholars. This paper introduces the history of Au nano-catalyst, its application in the engine exhaust emission purification and preparation methods of the Au nano-catalyst.
