Abstract

CO hydrogenation over a CeNi₂, an amorphous CeNi ₂H_x and a disproportionate mixture containing Ce hydride and CeNi₅ which were prepared by hydrogen absorption, has been investigated. Catalytic properties are different among the three samples since the bulk structure of the samples changes during the reaction. Nevertheless, the amorphous CeNi₂H_x exhibits high activity as well as unique selectivity of hydrocarbons. This study shows that hydrogen-induced amorphization (HIA) is a potential activation treatment for intermetallic compounds for catalysts.
