Remarkable activity of Ag/Al2O3/cordierite catalysts in SCR of NO with ethanol and butanol

- Ag/Al2O3/cordierite catalysts are very active in SCR of NO with ethanol and butanol.
- NO conversions are in the range of 95-99% at 250-430 °C.
- The properties of the catalysts depend on the silver content.
- Silver modifies redox and acid-base properties of the catalyst surface.
- Ag+ and Agnδ+ adsorb oxygen in quantities sufficient for alcohols partial oxidation.
