The work is devoted to the synthesis of silicon oxycarbide composite modified with titanium oxide by joint mechanical treatment of white soot and activated carbon with TiO2 particles deposited on its surface. The deposition of titanium oxide was confirmed by elemental analysis data. Scanning electron microscopy showed that the size of the particles does not exceed 100 nm. The structure of the obtained materials was studied using such methods as X-ray diffraction and IR spectroscopy. It was found that the silicon oxycarbide composite is highly amorphous; the XRD patterns displayed peaks, which can be attributed to the plane reflections of anatase. The investigation of the IR spectra showed the presence of bands corresponding to vibrations of Ti–O–Ti and Ti–O–C bonds. The porosity of the synthesized samples was studied using nitrogen low-temperature adsorption/desorption. It was revealed that the composite has a fairly developed porous structure with a predominance of meso- and macropores. The material is suggested to be used as a photocatalyst for the destruction of organic compounds in purification processes.
