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 the hcp-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 the hcp-typed structure in the middle range region. These experimental results suggested that the partially oxidized hcp-typed Ru(Ni) fine particles were obtained by the present leaching process.
