Title: Catalytic hydrogenolysis and dehydrogenation over copper-nickel alloys
Abstract: The hydrogenolysis of ethane to methane and the dehydrogenation of cyclohexane to benzene were investigated over a series of copper-nickel alloys. The alloys were characterized by adsorption, X-ray diffraction, and magnetic measurements. The effect of adding copper to nickel was very different for the two reactions investigated. In the case of ethane hydrogenolysis, the catalytic activity decreased markedly and continuously with addition of copper to nickel over the whole range of alloy composition, although much of the activity decline was observed on addition of the first few percent of copper. With cyclohexane dehydrogenation, however, the catalytic activity increased initially with addition of small amounts of copper to nickel, and then remained insensitive to alloy composition over a wide range, finally decreasing sharply at compositions approaching pure copper. The effects of alloying are clearly very specific to the nature of the reaction.
