Catalytic properties of nanosized Cu/Zr[O.sub.2] systems in the steam reforming of bioethanol

A size effect was found in the low-temperature steam reforming of bioethanol (15 vol. % ethanol in water) on copper catalysts supported on yttrium-stabilized zirconia: the specific rate of the conversion of ethanol into the key reforming product, acetaldehyde, is virtually independent on the mean di...

Summary:A size effect was found in the low-temperature steam reforming of bioethanol (15 vol. % ethanol in water) on copper catalysts supported on yttrium-stabilized zirconia: the specific rate of the conversion of ethanol into the key reforming product, acetaldehyde, is virtually independent on the mean diameter of the copper particles in the range 6-10 nm but drops significantly for particles with diameter 1-2 nm. Hypotheses for this observed effect are presented. Key words: temperature-programmed reduction, catalyst, copper, yttrium-stabilized zirconium dioxide, bioethanol, dehydrogenation, steam reforming.
