Structure of Pd Species and its Effects on Catalytic Activity

1 Sintering and Redispersion of Pd Species under Different Environments - To 

The redispersion phenomenon is not favorable with metallic Pd because it has a much larger wetting angle than the oxide. Therefore, contrary to the redispersion phenomenon observed under oxidation conditions, sintering of Pd particles has been generally observed upon reduction in H2 above 400 In the
