  • Abstract

    This paper presents a ?green? approach for the preparation of platinum (Pt) and gold (Au) nanoparticles and their self-assembled nanostructures by means of L-ascorbic acid and sodium carboxymethyl cellulose (CMC) as reducing and stabilizing agents, respectively. The self-assembly structures of Pt and Au nanoparticles such as Pt nanowires, Pt nanodendrites and Au nanochains were achieved by adjusting the experimental parameters. The synthesized metal nanostructures were systematically characterized with transmission electron microscopy (TEM), x-ray diffraction (XRD) and fourier transform infrared spectroscopy (FT?IR) techniques. The selected area electron diffraction, XRD patterns and the high resolution?TEM image confirm that the resulting metal nanostructures are highly crystalline and the structure is face?centered cubic (fcc). The FT?IR analysis suggests that the resulted metal nanostructures are stabilized with ?COO? (carboxylate) and ?OH (hydroxyl) groups in CMC molecules. It is also noted that the type of interaction between metal particle and carboxylate group is bidentate bridging. The present method provides a simple, cost?effective and eco?friendly strategy toward the fabrication of Pt and Au nanostructures.
