Preparation and Characterization of Cu–SiO₂ Nanocomposite

Abstract

Cu–SiO₂ nanocomposites have been studied to achieve hybrid structures at room temperature without an inert atmosphere. First, SiO₂ nanoparticles were synthesized by the sol-gel method. Second, SiO₂ nanoparticles deposited with copper (Cu–SiO₂) were prepared by the reaction of the SiO₂ nanoparticles and copper chloride at room temperature for 6 hrs with catalyst and without catalyst, respectively. Results showed that the SiO₂ nanoparticles with about 90 nm diameters were covered with Cu nanoparticles. The Cu–SiO₂ nanocomposites were investigated with TEM, energy dispersive X-ray spectroscopy analysis (EDS), and X-ray photoelectron spectroscopy (XPS).
