DS 30.3: Vortrag

Donnerstag, 14. März 2013, 15:15–15:30, H32

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.
