Porous Ag-Fe2O3 nanocomposite catalysts for the oxidation of carbon monoxide

- Porous Ag-Fe2O3 nanocomposites used as catalysts for CO oxidation.
- Ag loading have an effect on the catalytic CO oxidation activity.
- Ag ions dispersed inside Fe2O3 mesopores and on the support surface.
- Interaction between Fe2O3 and Ag as well as porosity of catalysts play important role.
- 7Ag-Fe catalyst can be reused at least five cycles without loss of activity.
