Abstract
The synthesis of catalyst K2Ti2O5+ K2Ti4O9/TiO2/TiO2+ SiO2/Ti for the oxidation of black carbon was carried out. The composition was prepared by the impregnation of an oxidized titanium surface with additionally modified sublayer consisted of anatase nanoparticles by potassium hydroxide. The initial and completion temperature of the catalytic soot afterburning process lays in the range of 340–550 °C and is in good agreement with analogous catalysts used in practice. The applied catalyst layer is resistant to adhesive and cohesive failure. It is characterized by a satisfactory resistance to thermal shock and the action of inhibitors.
