Preparation and Characterization of Platinum Nanorods Using Ascorbic Acid as the Reducing Agent

Abstract:

Nanorods of platinum with an average length of 500-1000nm have been prepared by a simple reaction between H₂PtCl₆·6H₂O and ascorbic acid in the presence of deionized gelatin at room temperature. Gelatin played a decisive role as an inhibitor of the direct reaction of ascorbic acid with H₂PtCl₆·6H₂O and coagulation of the growing platinum in producing the nanorods. In the absence of gelatin, we can only obtain irregular large platinum particles. The products were characterized by X-ray powder diffraction, scanning electron microscope and X-ray photoelectron spectra.
