Popis: 1. X-ray analysis, oxygen chemisorption measurements, and curves of the radial distribution of atoms have been used to study the formation of platinum particles on a: γ-Al2O3 surface in the presence of titanium. 2. The addition of Ti to the system affected the dispersity of the platinum particles in every case. This action arises from the preferential interaction with the added TiO2, and depends on the Pt and Ti concentrations.
