Morphologies of Sn and PtSn phases on thin films of alumina and graphite

Transmission electron microscopy studies of Sn and Pt-Sn morphologies were conducted on model catalysts, prepared by the vacuum evaporation of metal onto thin films of γ-alumina and sheets of graphite. All supported Sn samples showed nonwetting metallic particles following treatment in hydrogen. Sma...
