Synthesis of silver promoted CuMnOx catalyst for ambient temperature oxidation of carbon monoxide
The present research shows that the addition of silver (Ag), by the deposition-precipitation method, to a mixed CuMnOx catalyst can improve the activity of carbon monoxide (CO) oxidation. The CuMnOx catalyst doped with 3 wt.% Ag shows a higher catalytic activity as compared to the 1, 2, 4 and 5 wt.%...

| description | The present research shows that the addition of silver (Ag), by the deposition-precipitation method, to a mixed CuMnOx catalyst can improve the activity of carbon monoxide (CO) oxidation. The CuMnOx catalyst doped with 3 wt.% Ag shows a higher catalytic activity as compared to the 1, 2, 4 and 5 wt.% Ag doped samples. The loading of Ag could introduce new active sites into the CuMnOx catalyst and reduce its deactivation. The order of the optimal calcination strategies based on the performance of catalysts for CO oxidation is as follows: Reactive Calcination > Flowing air > Stagnant air. All the catalysts were characterized by XRD, FTIR, BET, XPS and SEM-EDX techniques. It was found that the high active surface area was one of the main factors for the high catalytic activity of the Ag-promoted CuMnOx catalyst.
