Temperature-programmed desorption was used to study the interaction of oxygen with both large (around 10 nm) and small ( < 2 nm) Rh, Pt and Pd particles supported on alpha -Al sub 2 O sub 3 (0001). The results indicate that O sub 2 desorption from small particles of Pt and Pd occurs at a signific...
