| Abstract: | Au/ZnO catalysts were prepared by co-precipitation.The effect of the amount of residual Cl-on Au/ZnO catalysts structure and CO oxidation performance has been investigated.The results indicate that Cl-can promote the glomeration of Au particle and the accumulation of carbonate-like species,therefore Cl-has negative effect on the activity and stability of CO oxidation. |
| Keywords: | Au/ZnO catalyst structure Cl-iron CO oxidation activity stability |
