Solar Photocatalytic Degradation of MCRR by Ag-Doped TiO2 Films
The photocatalytic degradation of MCRR has been investigated using Ag-doped TiO2 films as photocatalyst and sunlight as irradiation source. Ag-doped TiO2 films can significantly accelerate the degradation of MCRR both in distilled water and in lake water, although the efficiency in lake water was not good as in distilled water. The photocatalytic activity was affected by the number of coating cycles and the best performance was found in films prepared with five coatings. Solution pH can also significantly influence the photocatalytic degradation of MCRR, and acidic pH was more efficient for the degradation of MCRR.
