摘要：

Surfactant exchange: Compared to monometallic particles, ligand exchange on bimetallic systems is more challenging as complications can arise due to different binding affinities between the ligand molecules and the two metals. In colloidal bimetallic Co-Pt nanopartides (see figure, MHL: 6-mercaptohexan-1-ol) the treatment with thiols mainly leads to a loss of Co. (Figure Presented). © 2008 Wiley-VCH Verlag GmbH & Co.
