Preparation Of Magnetic Composite Photocatalyst And Its Photocatalytic Properties

Magnetic photocatalysts (TiO2 Fe3O4),which are liable to be separated and recovered, were prepared using FesO4 as support.The surface morphology and crystal pattern were investigated by means of XRD, SEN, XPS and FTIR.The results showed that TiO2 wraps on the surface of FesO4.The photocatalytic activity of the catalysts was investigated by photocatalytic decolorization of (TNR). The photocatalytic activity of the catalysts is high and the separating ratio is 93%.
