摘要：

Platinum nanoparticles (3-5 nm) dispersed on polycrystalline SnO2 (8-25 nm) thin films were obtained by codeposition of Pt and SnO2 from ultrahigh frequency spraying of a solution. SnO2 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/SnO2 films. A HREM study shows well crystallized nanoparticles with good interaction between Pt particles and SnO2 grains. Contrary to other noble metal particles, no icosahedral or decahedral morphologies due to multitwinning are observed. © 1993 Academic Press, Inc.
