摘要：
Carbon-modified photocatalyst was obtained by modification of the commercial anatase TiO2 (Police, Poland) in a pressure reactor in an ethanol atmosphere at 120 °C for 4 h. The activity was tested during monoazo dye decomposition under UV light irradiation (Reactive Red 198 with λmax = 516 nm). The reusability aspect of carbon-modified TiO2 photocatalysts was predominantly studied. Using the additional aeration process caused to stabilization the “decolourisation time” of aqueous solution of Reactive Red 198. To compare the activity of obtained material the commercial TiO2 P25 was used and only on its surface the presence of carbon deposits were observed.
