Resumo
Selective ethanol dehydrogenation using a Cu/Al2O3 catalyst was investigated by time-resolved XAS/MS/Raman techniques. On-line monitoring of the reaction products revealed that formation of H2 and acetaldehyde occurs over intermediate Cu+ species self-reduced upon reaction and the selectivity to ethyl acetate results in coupling of acetyl and ethoxy species over mixed Cu°/Cu+ active sites.
