Reforming of Ethanol with Carbon Dioxide Catalysed by Gold-promoted Copper-ceria-zirconia Composites

Abstract

Abstract In ethanol CO2 reforming, the addition of Au to 10Cu45Ce45Zr catalyst increased the conversion of ethanol and the yields of H2 and CO which were maximized for 2Au8Cu45Ce45Zr catalyst. TG-DTA measurement of used catalysts suggested that Cu metal species on the active catalysts would be difficult to oxidize, promote the transfer of oxygen to carbonaceous species forming CO and lead to the decrease in coke formation with addition of Au.
