Two series of alumina-supported Ni–Cu and Ni–Au catalysts were prepared by incipient wetness co-impregnation and characterized using nitrogen adsorption at −196°C, X-ray diffraction, hydrogen chemisorption, and temperature-programmed reduction methods. The presence of different alloy phases found in reduced Ni–Cu and Ni–Au catalysts was in fair agreement with the phases predicted by the thermodynamics...
