Abstract
Variously shaped gold nanoparticles were hydrothermally prepared by adding the cationic surfactant cethyltrimetylammonium bromide (CTAB) into the anionic surfactant sodium dodecyl sulfonate (SDS) in aqueous solution at 180°C without reducing agents and/or templates. Nanoparticle size and shape were controlled by the surfactant mixing ratio CTAB:SDS = x CTAB:(1 − x CTAB) and reaction time. Increasing CTAB concentration from x = 0.01 to x = 0.07 changes the nanoparticle shape from icosahedron to triangle or ellipse. The influence of the cationic/anionic ratio is presumably due to the differing catanionic micelle structures.
