Its Ea is 17.4 kcal mol-1 for the reaction on Pd55 and 34.4 kcal mol-1 for the reaction on Rh55. These results indicate that Pd particles are more active than Rh particles in propene oxidation, which agrees with the experimental findings. The larger Ea for Rh55 than that for Pd55 arises from the stronger Rh-OH bond than the Pd-OH bond. The higher energy d-valence band-top of Rh55 than that of Pd55 is the origin of the stronger Rh-OH bond than the Pd-OH bond. Thus, the d-valence band-top energy is an important property for understandin
