摘要
Ag nanoparticles were synthesized by thermal decompositon of an Ag-oleate complex by using an electric furnace (autoclave) at 300 degreesC for 4 hrs. The particles were characterized by using a UV-vis spectrophotometer, a transmission electron microscope (TEM), and an X-ray powder diffractometer (XRD). The synthesized Ag nanoparticles were used as seeds for Ag-TiO2 nanoparticles, which had core-shell structures. TEM images of the Ag-TiO2 nanoparticles showed that the silver core was coated with titanium oxide. Ag-TiO2 nanoparticles composed of a silver core (20-nm diameter) coated with titanium dioxide (less than 5 nm layer) were produced by a sol-gel process.
