Raney Ru has been found to be an effective catalyst for ammonia synthesis, isotopic equilibration reaction (IER) of dinitrogen, and CO hydrogenation. For such reactions, preparation conditions are important because they may affect surface structure. The authors have studied Raney Ru by XPS, TEM, and other techniques under various conditions. A Raney catalyst has a higher concentration of an active element than a supported catalyst and is more easily studied by XPS. A super high voltage transmission electron microscope (SHV-TEM) enabled them to observe the lattice structures of microcrystals in the metallic block. Although several works have been reported on the surface characterization of Raney Ni or intermetallic catalysts, no such work has been reported on Raney Ru catalyst.
