Synthesis and Characterizations of Monodispersed Nanotriangle of Gold

Article Preview

Abstract:

Monodispersed nanotriangles of gold have been prepared by a simple reaction between HAuCl₄·4H₂O, KOH and NH₂OH·HCl in the presence of gelatin. Gelatin played a decisive role as an inhibitor of the direct reaction of NH₂OH with AuCl₄- and coagulation of the growing gold in producing the triangle. In the absence of gelatin, we can only obtain irregular large gold particles. The products were characterized by X-ray powder diffraction, transmission electron microscopy and UV-visible absorption spectroscopy.
