This synthesis route yielded wurtzite ZnO, with Al being incorporated into the ZnO lattice at low doping levels. Al doping was found to alter the reaction pathway of ethanol steam reforming by suppressing the consecutive acetaldehyde conversion to acetic acid and further to acetone. Continuous kinetic experiments using a plug flow reactor resulted in almost full conversion and an acetone selectivity of 53% at 450\u00b0C over pure ZnO. Feeding acetaldehyde and acetic acid confirmed a consecutive multistep reaction network starting with ethanol dehydrogenation to acetaldehyde, followed by its conversion to acetic acid and a subsequent decarboxylative ketonization to acetone and CO\n                    <jats:sub>2<\/jats:sub>\n                    . Upon Al doping, the specific surface area increased by about a factor of two, but conversion was hardly changed. Instead, the acetaldehyde selectivity increased, whereas acetone and CO\n                    <jats:sub>2<\/jats:sub>\n                    formation decreased, indicating that Al incorporation selectively suppresses ketonization. Overall, acetone formation via ethanol steam reforming was found to be a strongly structure\u2010sensitive reaction over Al\u2010doped ZnO, with its surface acid\u2013base properties strongly depending on the Al content.\n
