Abstract

We have used Lithium Aluminum Hydroxide reducing method of silver nitrate to prepare heterogeneous silver-silica nanocomposite particles with thiol and amino groups serving to bind the Ag nanoparticles to the surfaces of the SiO₂ nanoparticles. We examined products of these reductions using FTIR, SEM, XRD and UV-vis. spectroscopy. The SiO₂ nanoparticles had diameters ranging from 70 to 90 nm; the Ag nanoparticles that formed on the surfaces of the SiO₂ nanoparticles had an average size of ca. 15 nm.
