The direct use of elemental sulfur as a reaction medium for the preparation of Au nanoparticles and vulcanized nanocomposites is described by J. Pyun et al. in their Communication on page 11 409 ff. Liquid sulfur serves multiple functions in this system—as a solvent, reducing agent, and colloidal stabilizer for the preparation of Au colloids. A tremendous excess of elemental sulfur is generated from petroleum refining, which creates new opportunities to use sulfur as a feedstock.
