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 PPh 3 , solubilize and reduce Au I 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.
