- Abstract:
- Silver nanoparticles were prepared from the nitrate silver solution in dodecyl
trimethyl ammonium bromide (DTAB)/sodium dodecylbenzenesulfonate
(SDBS)/polyvinyl pyrrolidone (PVP) complex solution with hydrazine as the
reductant. Scanning electron microscopy (SEM), X-ray diffraction (XRD) and
UV–Vis spectroscopic analysis were conducted to investigate the role of anionic–
cationic surfactants on the growth process of silver particles. The results showed
that, before the formation of spherical silver nanoparticles, the cube and then
tetrakaidecahedrons of AgBr were initially formed. It is concluded that the
selective interaction of bow-like electric double-layer structure of anionic–cationic
surfactants with certain crystallographic planes of crystals dominated the
morphology evolvement of the reaction products. In addition; the PVP coverage
finally encouraged the formation of well-dispersed spherical silver nanoparticles.
