Using Fenton-Reaction as a Novel Approach to Enhance the Photocatalytic Activity of TiO2-γ-Fe2O3 Magnetic Photocatalyst Undergoing Photo-Dissolution Process without Silica Interlayer

The photocatalytic activity of TiO2-gamma-Fe2O3 core-shell magnetic photocatalyst is known to be severely affected by the photo-dissolution phenomenon in the absence of SiO2 interlayer. We demonstrate here that the involvement of advance oxidation process, such as the Fenton-reaction, makes the same photo-dissolution process responsible for an enhanced photocatalytic activity.
