| Abstract: | Catalysts prepared through the interaction of C3H5PdC5H5 with the surface of evacuated Ho2O3/C after reduction by H2 at 573 K contain Pd and Ho2O3 particles whose size is 30 and 20–40 Å, respectively. XPS and TEM data indicate that Pd particles have a positive charge and their surface is partly covered by Ho oxide.
