Gold Nanoparticles on Polymeric Micro Beads: A One-Pot Synthesis and Characterization by X-Ray Absorption Near Edge Structure (XANES) Spectroscopy
Cetyl trimethyl ammonium bromide (CTAB) stabilized gold(III) salt in chloroform was reduced using NaBH4 in the presence of commercially available methanethiol-polyphoResinTM to obtain polystyrene micro beads with gold nanoparticles on their surface. X-ray Absorption Near Edge Spectra (XANES) of Au and S revealed S-Au bonding state. TEM studies coupled with Selected Area Electron Diffraction(SAED) patterns revealed the morphology of the Au nanoparticles on the surface of the micro beads.
