Transformation for high activity: Aqueous-phase reforming (APR) of ethylene glycol over alumina-supported Pt catalysts is reported. On heating and at high pressures, the alumina support transforms to AlO(OH) (boehmite). This phase transformation is studied in situ by using attenuated total reflectance IR spectroscopy. Pt/AlO(OH) shows excellent stability at APR conditions and allows efficient production of hydrogen. It is assumed that the high concentration of OH species on boehmite make it a promising support for catalysts.
