Synthesis of gold nanoparticles stabilized by 3-(aminopropyl)triethoxysilane through (N, N-dimethylformamide)reduction
gold nanoparticles were synthesized in DMF (N,N-dimethyltbrmamide) solution by using 3-(aminopropyl)triethoxysilane as stabilizer through wet chemical route.A characteristic surface plasmon band can be observed for the obtained gold nanoparticles from UV-vis absorption spectra,which indicate that KH-550 can serve as stabilizing agent for the formation of gold nanoparticles.The influence of reaction temperature,reaction time and precursor concentrations on the formation of gold nanoparticles is investigated through UW-vis absorption spectra.The results show that surface plasmon absorption peak could be red-shifted when reaction temperature,reaction time and precursor concentrations increase.Transmission electron microscopy (TEM) results show that the obtained gold nanoparticles with spherical morphology have a narrow size distribution.
