N2 - The catalytic behavior and stability of rhodium supported on pure and La-doped alumina were studied towards the CO oxidation reaction. Diffusion of Rh3 + ions into the bulk of support was shown to cause rapid deactivation in both cases. Alumina doping with La leads to modification of the alumina donor sites, concentrating of Rh near such sites, and acceleration of Rh3 + diffusion process. Diffused Rh ions were shown by means of photoluminescence to localize in the nearest coordination environment of the La ions in La-enriched alumina starting from a calcination temperature of 800 °C.
