The results indicated that adsorbability of CB-TiO2 was greatly improved, BET specific surface area of which enhanced 50%-80% than that of TiO2, baked under 300 degrees C-500 degrees C. And CB modification reduced the crystal grain size, so the temperature of phase transformation was decreased. Corresponding, the photocatalytic activity of CB-TiO2 also was greatly improved, the reaction rate of which was 1.5 times of that of TiO2. %K photocatalytic oxidation %K TiO2 thin film %K carbon black modification %K specific surface area %K XRD %K DRS
