Potassium-incorporated manganese oxide enhances the activity and durability of platinum catalysts for low-temperature CO oxidation

Potassium ions in the tunnel of MnO 2 is demonstrated to significantly enhance the activity of surface oxygen species, which is favorable for preparing highly efficient Pt-based catalysts for low-temperature CO oxidation. Potassium-incorporated manganese oxide is demonstrated as an efficient support...

Zusammenfassung:Potassium ions in the tunnel of MnO 2 is demonstrated to significantly enhance the activity of surface oxygen species, which is favorable for preparing highly efficient Pt-based catalysts for low-temperature CO oxidation. Potassium-incorporated manganese oxide is demonstrated as an efficient support for fabricating highly active and stable Pt catalysts for low-temperature CO oxidation.
