Ambient temperature oxidation of carbon monoxide using a Cu2Ag2O3 catalyst
- 128 Downloads
The mixed copper–silver oxide, Cu2Ag2O3, has been prepared by co-precipitation and tested for ambient temperature carbon monoxide oxidation. The catalyst demonstrated appreciable low temperature oxidation activity and the catalyst aged for 4 h was the most active. Carbon monoxide conversion increased with time-on-stream, reaching steady state after ca. 1000 min. A␣comparison of the catalytic activity has been made with a representative sample of a high activity hopcalite, mixed copper/manganese oxide catalyst. On the basis of CO oxidation rate data corrected for the effect of catalyst surface area the Cu2Ag2O3, aged for 4 h was at least as active as the hopcalite.
