Abstract
The high energy ball-milling technique has been used to produce metast able Ni(Ru) alloys supported on alumina. This catalyst has potential a pplication for the hydrogenation of the C=O bond. The active species a re first formed by mechanical alloying pure Ni and Ru powders. The alu mina support is ground independently until no structural transformatio n occurs. Finally, the supersaturated Ni(Ru) powder is milled with the alumina support to produce highly dispersed individual Ni(Ru) nanocry stals on the surface of Al2O3. This supported catalyst has been charac terized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy and thermal desorption spectroscopy.
