Surface diffusion of oxygen species on supported metal catalysts

Surface diffusion of oxygen species on supported metal catalysts 

Rhodium is the metal having the highest 02 - - 02 equilibration rate on alumina (Table 2). There are many indications in the literature that this 

Similar results were obtained with other supports such as silica, alumina, magnesia ceria. It was also verified that the direct exchange between the gas phase and the support could not occur at a significant rate on most oxide supports. TPIE were carried out on the bare supports and
