| Abstract: | Stable and nearly monodispersed gold nanoparticles with sizes of 2.8–4.7 nm are easily prepared by the reduction of tetrachloroaurate salts in a toluene-water system in the presence of 1-R-5-thiotetrazoles (R = Et, t-Bu, 1-adamatyl). The prepared gold nanoparticles were characterized by TEM, XRD, UV–Vis, FTIR and TGA. |
