Characterization of bimetallic Pt-Sn/Al{sub 2}O{sub 3} catalysts: Relationship between particle size and structure
- Institut Francais du Petrole, Rueil-Malmasion (France); and others
Pt-Sn/Al{sub 2}O{sub 3} bimetallic catalysts have been prepared using organometallic precursors and characterized. Two models depending on average platinum particle size are proposed in order to describe these solids. The catalyst obtained from a highly dispersed monometallic precursor may be described as Pt/SnO{sub x}/Al{sub 2}O{sub 3} with platinum probably in interaction with tin oxide. When the monometallic precursor has low dispersion, the bimetallic system may be described as PtSn{sup 0} + SnO{sub x}/Al{sub 2}O{sub 3}. 35 refs., 8 figs., 9 tabs.
