Title
Low temperature carbon monoxide oxidation over nanosized silver doped manganese dioxide catalysts
Abstract

Nanosized silver doped manganese dioxide catalysts have been prepared and tested for CO oxidation reaction at lower temperature. Silver doped manganese dioxide catalysts show higher CO conversion as compared to undoped manganese dioxide. Under the influence of excess oxygen catalysts are stable and show good activity. From time on stream experiments it is clear that the catalysts are highly stable for CO oxidation for a longer period in absence of moisture as well as in presence of moisture in the feed gas. The catalysts show higher activity for CO conversion in presence of moisture, indicating that moisture facilitates CO oxidation reaction on the catalyst surface.
