Abstract
Pd was deposited from a filament onto an α-Al2O3 single-crystal. The Pd 3dP 5/2 binding energy change versus deposition time was used as a calibration of the Pd clusters size. The experiment was then reproduced on γ — Al2O3. The Pd 3d 5/2 binding energy showed that the clusters growth mechanism was now different. Thermal treatments produced a dispersion of the metal or a clusters size increase depending on the temperature or the nature of the support. Oxygen exposure dispersed Pd in every case. A mechanism is proposed to interpret this phenomenon.
