Composition and Chemistry of a Pd-Ni-Co thin film alloy studied by HAXPES — •Julius Kühn1, Andreas Lippitz1, Mihaela Gorgoi2, Kai Nörthemann3, Werner Moritz3, and Wolfgang Unger1 — 1BAM Federal Institute of Materials Research and Testing, Berlin — 2Helmholtz Zentrum Berlin — 3HU Berlin
The surface near region is very important for catalytic processes. Compositional changes, e.g. segregation of alloy constituents in states before and after hydrogen sulfide exposure was investigated by non-destructive chemical HAXPES depth profiling. The HAXPES data are completed by results of AES providing data characteristic of the uppermost surface and EDX data characteristic of the bulk of the alloys.
