Using fenton-reaction as a novel approach to enhance the photocatalytic activity of TiO2-gamma-Fe2O3 Magnetic photocatalyst undergoing photo-dissolution process without silica interlayer

Abstract

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.
