Photodegradation of Methyl Orange with Fe_3O_4/SrTiO_3 Composite Photocatalyst

SrTiO3 photocatalyst and Fe3O4/SrTiO3 composite photocatalyst were prepared by using co-deposition method.The samples were characterized by means of UV-vis diffuse reflectance spectrometry,XRD,and SEM-EDX.Photocatalytic activity was evaluated with photodegradation of methyl orange.The results indicate that Fe3O4 doping increased visible light absorption of SrTiO3 photocatalyst obviously,which enhanced photocatalytic performance of SrTiO3 photocatalyst.The photocatalytic activity of the 10% Fe3O4 doped SrTiO3 photocatalyst is three times as much as that of pure SrTiO3 photocatalyst in terms of the photodegradation of methyl orange.
