The X-ray photoelectron spectroscopic study of Raney and Urushibara nickel catalysts activatede under various conditions was undertaken to chyrycterize the surface state of the catalysts including thecatalists' structure.Raney nickel catalysts contain both oxidized and metallic aluminium in the activated phase.As for Urushibara nickel catalystsdigested with acetic acid or sodium hydroxide, metallic and oxidized zinc were observed in the catalysts surface.Based on the X.p.s. peak intensities for the catalysts, the structure of Urushibara nickel catalysts was found to be that of a supported catalysts, whereas Raney nickel catalysts showed X.p.s. features consistent with those expected for skeletal nickel catalysts.
