Abstract

CeO2 supports were prepared via a dealloying method from amorphous alloy. The activities of Ru/CeO2 catalysts were examined in the hydrogen generation reaction from ammonia borane. To investigate the effects of atomic arrangement of CeO2 precursor on the activities of Ru/CeO2 catalysts, CeO2 supports were prepared from amorphous alloys and crystalline alloys. The use of amorphous alloys as the precursor of CeO2 created fine porous structures, resulting in high catalytic activities of Ru/CeO2 catalysts.
