Bimetallic Ag-Pt and Au-Pt aggregates synthesized by radiolysis

Abstract

Irradiating aqueous solutions containing both Ag{sub 2}So{sub 4} and K{sub 2}PtCl{sub 4} leads to intermetallic aggregates of various sizes according to the stabilizing agent: polyvinylalcohol, polyacrylic acid or polyacrylate. In the last case, the particle diameter is 1.5 nm. The bimetallic character is evidenced in all cases by the spectral changes of such sols compared to pure silver sols which display a characteristic surface plasmon absorption band. This plasmon band disappears when 10 to 20 at.% or more Pr is present. Observation by TEM gives an estimation of the particle sizes. Comparable results have been obtained for Au-Pt particles.
