文摘

Highly active Ag/Ce-Zr catalyst with ‘Ag/Ce’ structure was successfully synthesized. Precipitant can affect the size of Ag particles and alter Ag-Ce interaction. The optimal interaction was beneficial for the increase of superficial Ag+ species. The catalyst/soot contact for the Ag/Ce-Zr catalyst is expected to be enhanced. Ag/Ce-Zr catalyst was utilized five times without any appreciable loss of activity.
