One-path and Selective Conversion of Ethanol to Propene on Scandium-modified Indium Oxide Catalysts

Abstract

Abstract The direct and stable conversion of ethanol to propene with yields up to 60 mol % was achieved on scandium-modified indium oxide catalysts at 823 K in the presence of water and hydrogen. The reaction pathways are also suggested, ethanol → acetaldehyde → acetone → propene, which is quite different from those on zeolites and on nickel ion-loaded silica catalysts.
