چکیده مقاله:

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 SiO۲ nanoparticles. We examined products of these reductions using FTIR, SEM, XRD and UV-vis. spectroscopy. The SiO۲ nanoparticles had diameters ranging from ۷۰ to ۹۰ nm; the Ag nanoparticles that formed on the surfaces of the SiO۲ nanoparticles had an average size of ca. ۱۵ nm.
