Controlled Synthesis of Two-Dimensional Networked Gold Nanowires and Microkites by Sodium Carboxymethyl Cellulose-Surfactant Soft Template

Abstract

A novel soft template method is reported to control gold nano or microstructrues. Gold nanowires with two-dimensional (2-D) network structure were prepared by anionic polymer (sodium carboxymethyl cellulose, CMC) reduction of HAuCl4. Big gold microkites were synthesized using CMC-cationic surfactant (dodecyl trimethyl ammonium chloride, DTAC) templates. Quasi-sphericSubscript textal gold nanopartilces were obtained through CMC-anionic surfactant (sodium dodecyl sulfate, SDS) templates. Electron diffraction suggested that the 2-D networked nanowires and microkite heads were single crystalline. Ultraviolet visible (UV-vis) absorption spectrum of gold structure obtained showed that there were anisotropic structure formed in reacted solutions. It is potential method to gain preferred noble metal structures by this soft template.
