Change in composition of surface layer of palladium-rhodium alloys during catalytic reaction
- 18 Downloads
A substantial enrichment of the presurface layer in rhodium of palladium alloys, containing 5 and 10% Rh, after cyclohexane was dehydrogenated on them, was detected by the x-ray photoelectronic spectroscopy (XPES) method.
Enrichment of the surface of the foil in rhodium is accompanied by an increase in the dehydrogenation rate of cyclohexane to benzene.
