摘要：

Here, a simple and general approach was developed for depositing metal nanoparticles on alkanedithiol self-assembled monolayers (SAMs) based on the spontaneous reduction of metal ions by the free SH sites of SAMs. By immersing the alkanedithiol SAM/Au in a corresponding metal containing solution (HAuCl4, AgNO3, H2PtCl6 and PdSO4), Au, Ag, Pt and Pd clusters, respectively, could be formed on top of the SAM/Au(111) electrode surface, which was confirmed by STM characterization. The size, morphology and coverage of clusters/islands can be tuned by modulating the immersion time, which allows for possible utilization of the metal/SAM/Au(111) in catalysis, nanoelectronics and biodetection.
