Effect of the Synthesis Method on Alumina Supported Silver Based Catalyst for NOx Selective Reduction by Ethanol

Alumina supported indium oxide, silver or bimetallic Ag-In catalysts with metal loading of ca. 2.5 wt% were prepared by excess solvent impregnation or incipient wetness impregnation. The influence of the impregnation was studied by testing the catalysts in DeNO(x) activity with ethanol in Lean Burn Conditions.
