Platinum nanoparticles (3-5 nm) dispersed on polycrystalline SnO[sub 2] (8-25 nm) thin films were obtained by codeposition of Pt and SnO[sub 2] from ultrahigh frequency spraying of a solution. SnO[sub 2] grain size decreases as the platinum concentration increases (0-11%). A comparison is made with pure platinum films where Pt grain size (20-40 nm) is much greater than in Pt/SnO[sub 2] films. A HREM study shows well crystallized nanoparticles with good interaction between Pt particles and SnO[sub 2] grains. Contrary to other noble metal particles, no icosahedral or decahedral morphologies due to multiwinning are observed. 18 refs., 6 figs.
