Abstract
Get yellow: The utilization of elemental sulfur as an unconventional medium for the synthesis and stabilization of colloidal gold is reported. In this system, sulfur serves multiple functions to sulfurate PPh3, solubilize and reduce AuI precursors into Au nanoparticles (NPs; see picture). Direct vulcanization of sulfur dispersions of AuNPs afforded cross-linked nanocomposites as confirmed by TEM, XRD, XPS, and Raman spectroscopy.
