Conclusions

  1. 1.

    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.

     
  2. 2.

    Enrichment of the surface of the foil in rhodium is accompanied by an increase in the dehydrogenation rate of cyclohexane to benzene.
