关键词:Au/13X ,催化剂,CO,氧化Study on Au/13X Catalysts for CO Oxidation Abstract: Gold catalyst was prepared using 13X Zeolite as the support
The effects of preparation conditions on the catalytic activity for CO oxidation were studied
When the pH value of chloroauric acid solution at 6, impregnation temperature at 80℃, the activity of Au/13X was better
The chemical modifacation of 13X and the addition of Fe could improve the activity of Au/13X
The catalyst was characterized by XRD, XPS and SEM
It showed that the modifacation of 13X and the a
