Synthesis and characterization of Ag and Ag-SiO2 nanoparticles

Ag-SiO2 nanoparticles were fabricated by the well-known Stöber method. Results show a dense coverage of silica nanospheres of about 200 nm size with homogeneously arranged Ag nanoparticles deposited on SiO2 nanoparticles. Ag-SiO2 nanoparticles were investigated with TEM images, EDX spectrum, UV-vis spectrophotometer.
