Abstract
Rh//gamma-Al2O3, Rh/SiO2, Pd/ gamma-Al2O3 and Pd/SiO2 catalysts with a metal content lower than 2.5%, supported by the incipient wetness met hod, were studied by electrophoretic method. It has been proved that t he metal is preferentially located at the periphery of the particles o f the support. It was proved, moreover, that the highest interaction b etween these metals and these supports is observed in the Rh/gamma-Al2 O3 system, while the lowest is observed in the Pd/SiO2 series; the int eraction between Rh and gamma-Al2O3 is greater than between Rh and SiO 2.
