Abstract

Unique, porous gold nanobelts consisting of self-organized nanoparticleswere synthesized in a high yield bymorphologypreserved transformation from metal-surfactant complex precursor nanobelts formed by a bolaform surfactant dodecane- 1,12-bis(trimethylammonium bromide) (N-C ₁₂-NBr ₂) and HAuCl ₄. It was revealed that the precursor nanobelts of the stoichiometric N-C ₁₂-N(AuCl ₄) ₂ complex formed through electrostatic combination of the positively charged quaternary ammonium headgroups of N-Cn-NBr ₂ and the negatively charged AuCl ₄ - ions. They were subsequently converted into porous gold nanobeltswith shrunken sizes upon reduction by NaBH ₄. The morphology of the produced gold nanostructures could be adjusted by changing the mixing ratio between N-C ₁₂-NBr ₂ andHAuCl ₄ in the reaction solution. It was found that the obtained porous Au nanobelts exhibited enhanced catalytic activity toward reduction of 4-nitrophenol compared with solid gold nanobelts, probably owing to their larger surface area and more active sites.
