Abstract

Two Pt-Sn/vulcan carbon nanocomposites containing nanoclusters of PtSn (niggliite) and Pt ₃Sn highly dispersed on a carbon powder support have been prepared using Pt(SnPh ₂Cl)(PPh ₃) ₂(Ph) or {Pt ₃[μ-(PPh ₂) ₂CH ₂] ₂(μ ₃SnF ₃) (μ ₃-CO)}[PF ₆] as single-source precursors of metal alloy. PtP ₂ or Pt metal is also present as a secondary phase. Bimetallic Pt-Sn nanoclusters with an average diameter of 5-8 nm are formed at a total metal loading of ca. 15 wt %. Evaluation of both Pt-Sn/C nanocomposites as electrooxidation catalysts in a direct methanol fuel cell gives fuel cell performances comparable to that expected for Pt-Sn catalysts prepared by more conventional methods.
