Mechanistic insight into the Brust-Schiffrin two-phase method for organochalcogenate-protected metal nanoparticles
Thesis (Ph.D.)--Georgetown University, 2011.; Includes bibliographical references.; Text (Electronic thesis) in PDF format. The primary objective of this thesis research was to explore the mechanism of the Brust-Schiffrin two-phase method, which has been widely used for preparing the thiolate-protected metal nanoparticles with the core diameter less than 5nm; to synthesize and characterize the ligand-protected gold nanoparticles using dialkyl ditelluride with different alkyl chain length as ligand precursor; and to develop a new synthetic route for obtaining ultra–small (< 2 nm) gold nanoparticels covered by tellurium-anchoring ligands.
