Abstract

Structures of Raney Ru(Ni) Fine Particles Were Investigated by High-Energy X-Ray Diffraction Coupled with Anomalous X-Ray Scattering (AXS) at the Ni K-Absorption Edge. Raney Ru(Ni) Fine Particles Were Prepared from Monoclinic-Al13(Ru,Ni)4, by the Leaching with Naoh Aqueous Solution. Ordinary PDF for Raney Ru Indicates Atomic Correlations Similar to those for Hcp-Ru. However, a Correlation Peak at about 0.2 Nm which Could Not Be Described by the Atomic Correlations in thehcp-Typed Structure Is Developed as a Function of the Ni Content. The Environmental RDF around Ni Clearly Reproduced this Interesting Correlation Together with an Indication of thehcp-Typed Structure in the Middle Range Region. These Experimental Results Suggested that the Partially Oxidizedhcp-Typed Ru(Ni) Fine Particles Were Obtained by the Present Leaching Process.
