Abstract

In this work, the TiO₂@Ti_xC_yO_z nanocomposite was obtained by adding a buffer gas to the initial mixture of reagents by the pulsed plasma-chemical method. Argon was used as a buffer gas. Pulsed plasma-chemical synthesis was realized using a TEA-500 electron accelerator. The physicochemical properties of the obtained TiO₂@Ti_xC_yO_z nanocomposites (morphology, average particle size, elemental, and phase composition) were studied. It was shown that by changing the buffer gas concentration, it was possible to control the phase composition, particle size, and shell thickness of TiO₂@Ti_xC_yO_z nanocomposites. The values of the band gap were calculated for the synthesized TiO₂@Ti_xC_yO_z nanocomposites. The photocatalytic and adsorption properties of TiO₂@Ti_xC_yO_z nanocomposites were studied.
