| Sumari: | Title screen The CuxOy@SiO2 and CuxOy@TiO2 nanocomposites attract the attention of researchers because of their photocatalytic, optical, and conductive properties. Promising markets for synthesized nanocomposites are medicine, chemistry, ecology, catalysis, additive technologies, and construction. The field of application is determined by the basic physicochemical properties of the composite, which in turn depend on the synthesis conditions. The effect of the addition of a buffer gas (argon) in the pulsed plasma-chemical synthesis of CuxOy@SiO2 and CuxOy@TiO2 nanocomposites on the morphology, size, phase, and chemical composition was studied in this research. Pulsed plasma-chemical synthesis was realized using a TEA-500 electron accelerator. The physicochemical properties of CuxOy@SiO2 and CuxOy@TiO2 nanocomposites were studied by various techniques such as energy-dispersive x-ray, transmission electron microscope, and x-ray diffraction. The morphology of the synthesized particles of CuxOy@SiO2 nanocomposite was close to spherical. The CuxOy@TiO2 nanocomposite was found to be a composite with the structure of core (titanium oxide nanoparticle)/shell (copper oxide). With the addition of argon to the initial mixture, the average particle size of the CuxOy@SiO2 and CuxOy@TiO2 nanocomposites decreased. The phase and elemental compositions of the CuxOy@SiO2 and CuxOy@TiO2 nanocomposites varied depending on the argon concentration in the initial mixture of reagents.
